Jetbeam RRT01 Review 2020 Version (Rotary EDC, Nichia LED, High CRI, 950 Lumens)

Jetbeam has a new version of the RRT01 Raptor out for 2020. If you remember back to last summer I reviewed the 2019 version of the light and loved it. The 2020 version adds an Optional Nichia emitter and changes how the rotary ring and UI work as well as being more flexible with different battery versions. Thanks to JetBeam for sending this to me to look at and review.

Versions

There are now 3 versions of the Jetbeam RRT01 that all share the same name. There is the original from about 8+ years ago, the 2019 version and now the 2020 version. Each having their own differences in performance, batteries, and LED. I do wish JetBeam would have added a V1, V2, V3 or used a different name with the light so it was easier for the consumers to tell the difference. The easiest way to tell the difference between the 2019 and 2020 is to look at the tail. The 2019 has a place for 3 tritium vials, whereas the 2020 has a button on the tail cap.

 

Packaging & Accessories

The packaging of the RRT01 is very Jetbeam, it’s a blue and black retail hanging package with all the details you need on the outside and side panels. As far as accessories, it depends on the version you get. My kit has the optional 2x extensions tubes that allow you to use 18500 and 18650 batteries in the light. In addition to this  it comes with a 1100mAh JetBeam branded 18350 battery with microUSB charging onboard, 3 extra  orings, an allan key, 2 extra screws for the clip (Not torx), and replacement rubber boot for the rear switch in gray. You also get a lanyard, manual, and other paperwork. 

 

Construction

The light is made from aluminum and anodized a warmer light gray with the control bezel being a silver. It’s nice to see a different anodizing color here. Machining is very good. Starting at the tail, there is a bezel around the center mechanical on/off button. When the button is in the off state the light doesn’t tail stand super well, but when the light is on the button has retracted enough that it tail stands great, so really a pretty thoughtful design as it helps you find it when you want to turn the light on. 

The body section of the light has knurling around it with 2 flats with the minimal labeling on each side. The light then grows to match the size of the head and control ring. Threads are wide, square cut and non anodized. By default the light will fit 18350’s and CR123A batteries which are great sizes for EDC but if you want more runtime you can insert one of the extensions and use a 18500 if you have them or add both if you want to use a 18650. Just remember to use a protected battery as this light doesn’t have LVP. When the extension are in place it’s a little less elegant I think and heavy in the head. 

 

The rotary control ring has some areas milled into it to give grip. It has a detent on both ends of the control area. From 0 to 100% is about 160 degrees of rotation. There is no detent in the control ring for the 2020 version of the light. The ring moves quite easily, I would like to just touch more resistance. The rotary really allows you to dial in the exact amount of light you want very quickly.

The head has an aluminum bezel that’s mostly built into the light and not proud. It is not glued but you will need a tool to get it loose. The glass lens is double anti reflective coated and it has a deep reflector with a light orange peal.

 

Size & Weight

I measured the length at 91mm in it’s shortest configuration. Each extension adds 15mm to the overall length of the light. Maximum diameter on the head of the light is 26mm, and minimum diameter at the head is 24.5mm. The extensions are slightly larger in diameter coming in at 26.46mm vs the 26mm of the head of the light. 

Weight in it’s shortest configuration with the included battery and clip is 114.6g. With a 30Q and the 3x extensions came in at 153.9g. 

 

Comparisons

The most obvious comparison with the RRTR01 2020 is the 2019 version and the lights look very similar. The largest difference is that the 2019 version is shorter without the tail switch. The lens’s are a little different too, the 2020 lights lens has a light orange peel and is deeper and the bezel is smooth. The diameter of the head is slightly longer too. The extension tubes fit either light. When you put the extensions on the light looks a little funny to me, it seems longer and the proportions are just off a little. For an 18650 light it’s a little on the long side when compared to the FW3A. 

 

Retention

The RRT01 like it’s predecessors are using the “standard” steel flame pattern clip meaning most aftermarket clips on the flashlight market should fit here. THe stock clip is a little longer than many at 61mm. The screw holes are hex head instead the more common torx. 

 

In the pocket it carries reasonably well. The slotted tail bezel that’s around the tail button sticks up a little more then I want but does protect the button well from accidental activation. It’s still deep enough I consider it deep carry. I found the short length to be about perfect in the pocket, it’s doable to carry with the extensions on and an 18650 but it’s center of gravity is more to the head. 

 

LED & Beamshots

There are 2 LED’s offered in the RRT01 Raptor (2020), a Cree XP G3 offering 80 CRI, and a Nichia 219C at 90CRI. I have the latter and it’s a nice warm 4000k. For me this is a great combination of tint and high CRI. JetBeam claims both are rated for 950 lumens, and that would be higher then I would expect out of a Nicha 219C as they typically don’t put out quite as much light as the Cree XP G3, so I take that with a grain of salt. It’s enough light to do the job easily. The beam here is nice for EDC, it has some center spot, about 20% of the beam and then fades to a useful spill. The rotary is very smooth and makes this light infinitely variable sub lumen up to 950. See the video version of this review for my Nightshots.

 

Heat and Runtime

Runtime here is very linear, I started my test with the included 1100mAh 18350 battery on full power. Output here was very linear and seems to not be regulated super well. There really isn’t much of a stepdown and the light ran above the 40% relative output out until 28 minutes. At 34 minutes the light shut off when LVP on the battery kicked in at 2.94V. The runtime here surprised me a bit, it’s rather short but then again this light doesn’t have much of a step down. It does get warm and the highest temp I saw was 59C around the 17 min mark. 

I then tested with a 3000mAh 18650 battery. You need to use a protected battery with this light, I didn’t do that my first test and the result was the light ran until the cell was dangerously low right at 1V. I was not happy about ruining a battery here, but the result was significantly longer runtime. FL1 was at about 95 minutes, total runtime was just at 1 hour and 40 minutes. You can see thermal regulation kick in at the top end a bit. 

 

UI

UI here is pretty unique to most other flashlights but it works pretty well. The RRT01 2020 version adds an on off switch at the tail of the light and combines with the rotary function in the head to change the brightness of the light. Once on rotate the ring to the right to increase in brightness, increase to the left to decrease in brightness. It is truly infantly variable as fast or as slow as you want. On my light I can turn the ring about 1/12 of the way before the LED begins to turn on. 

 

This light does have an infinitely variable SOS and strobe modes as well. When on just rotate to to the maximum brightness setting and then to the left slightly 3 times and you get SOS, do this 4 times to get strobe. You can then dial back the brightness if you want. To exit just turn the light off and it goes back to normal.  

 

Recharging

The light includes a 1100mAh Jetbeam branded 18350 battery that has onboard microUSB that you plug into the side of the battery. It has a multicolor LED on top that goes red when charging and green when charged. LVP is built into the battery and it stopped at 2.94V. Charged it stopped at 4.16V. When I plugged it in to charge I did notice the top of the cell got pretty warm, about 110F but this quickly dissipated. My guess is it’s doing this at first to gradually limit current going into the battery at the start of a charge. Overall the battery took 92 minutes to charge, and the maximum charge rate I saw was around the 70 minute mark at 1A. It’s a little odd to see that high of charge rate at the end of the charge cycle. 

 

Pro’s

  • Nichia LED, my biggest complaint with the 2019 version of this light was the LED that was chosen.
  • I am a sucker for a rotary interface, it works here well but requires shifting your grip to turn on then adjust the output.
  • I like the anodizing color here, a warm gray, almost sand color.
  • Nice overall EDC light with options to go to 18650 too.

 

Con’s

  • No Low Voltage Protection, must use protected cells if you plan to run the battery to exhaustion,. . 
  • A little awkward with the extensions installed, it throws the balance way forward.
  • Confusing naming with the previous versions of the light.
  • On the expensive side with the extension kit

 

Conclusion

The JetBeam RRT01 is the 3rd irrieteration of the light that shares the same name, while confusing for customers it’s a light I am enjoying. I really like rotary interfaces, I think they should be done on more flashlights as it’s intuitive and easy to operate for people of any age. The addition here of the on/off button on the tail instead of detents in the rotary makes the light less likely to come on in a pocket or when not in use but I think detracts from the overall rotary aspect of the light That said it still works pretty well but just requires you to change grips when using the light to turn it on and adjust the output.

The inclusion on some version with the extensions is smart, allowing you to use more battery types, it’s kind of an after though on design but it works reasonably well, especially if you want the extra runtime of an 18650, just be sure to use a protected battery since the light itself doesn’t have LVP. 

The optional Nichia 219C emitter here is great. One of the features I liked least about the 2019 version was it was cool white and it’s great Jetbeam listed to this user feedback myself and others had. Overall this is a fun edc light, it’s a little on the expensive side but one I can still recommend. Make sure to check my links in the description as I will list any coupons or sales I get where you might be able to get a discount.

Olight i5T Cu Review (AA, 300 Lumens, Raw Copper, Great EDC)

Olight has another raw copper light out for all you copper fans with the Olight i5T Cu. This is a special edition of the i5T which has been released in several different editions in 2020. It’s a 2 mode light taking a AA battery with a deep cary pocket clip. It’s similar to the Olight i3T but larger. Thanks to SkyBen for sending this to me to review.

Versions

There are a couple of versions of the i5T from Olight. There as a Shot Show edition they gave out to people, it was aluminum with a neutral white emitter, A CoVID relief special edition that was sold, it was aluminum and had some blue anodized accents on it, a normal black anodize and desert tan models, and the one I have here the in copper. Everything except the shot show edition has the standard cool white emitter. 

Packaging and Accessories

The i5Tcu came in what I would call a gift box. It’s a heavy duty white cardboard that’s finished nicely with a color photo on the front and a limited amount of details on the back. Inside the light was vacuum sealed in plastic with an anti oxidizer packet to prevent any patina from forming until it arrives in your hands. The only included accessory was the manual and GemTec AA battery that came preinstalled. 

Construction

No complaints here on construction quality, Olight does a nice job with these, and is one of my favorites when it comes to their raw copper machining. Everything is nicely chamfered, and polished. It also comes in the least oxidized state of any of the copper flashlights I have. The overall design here is a largely a scaled up version of the Olight i3T with a few differences. At the tail the buttons appear to be the same, as the i3T. The proud switch has a hard plastic edge and then a rubberized grip at the very top. It takes quite a bit of force to active the switch which I like. This one won’t come on in your pocket on accident. I do feel a bit of cell movement internally when pressing the switch which feels a little unnatural. 

The knurling on the tail cap is mostly horizontal with just a touch of vertical, mine seems to be not perfectly centered, like it is on the i3T. Not sure if this is intentional or just a slight manufacturing issue, either way it adds a nice amount of grip to unscrew the tail for battery replacement and style. Internally the tail section is made of copper too, and has nicely cut square threads that need a bit of grease.

The pocket clip is push on style but fits tightly, more on retention in a minute. The body itself has the double line spiral as the i3T does. It’s fairly deeply cut and the walls have minimal chamfer. It’s mostly for style but adds some grip to. The head is very plain, it has the model number and serial engraved into it and does not appear to come apart or it’s a one piece design. The lens appears to be plastic and be a one piece with the optic and reflector.

 

Size & Weight

I measured the length of the light at 95.5mm, diameter at 17.9mm and weight with an Amazon Basics High Capacity NiHM and clip at 112.3g. It’s a pretty heavy light, but that’s what you expect for copper

When I compare it to other similar lights I have, the diameter is a little smaller than my Reylight Pineapples or Ti LAN or the copper variants. Length wise it’s a little shorter too. If you liked the Olight i3T it’s just a little longer and slightly larger in diameter. It’s fairly comparable in size to the Olight M1T Raider, but smaller diameter and slightly longer. 

 

Retention

Retention on the i5T is good. I like to EDC 14500 lights, they are a good balance of size, weight, and most importantly diameter. This is especially true when I am wearing shorts. The i5T has a reasonably deep carry pocket clip, and on the copper model it’s a bronze PVD colored finish that fits pretty well especially after the light takes on some patina. It has a reasonable amount of room for material at the top too. It is using Olights dual direction clip which some love to hate. I will say my original clip on my i3T did snag not go back into shape. Olight did offer a replacement but it was only available in black, not the original PVD bronze copper it came with. It would be kind of nice if Olight included an extra clip with these special editions since they don’t seem to have spares.

 

LED & Beamshot

The i5T Cu here is running an Osram P9 LED in cool white. That said it’s not Olights typical 6500k, it’s warmer and more neutral, I would guess somewhere about 5500k or so. It does have a bit of a green tinge. The beam is using what Olight calls a PMMA lens. It creates a beam that is mostly a spot, with minimal flood. Good for EDC. There is a bit of PMW on low according to my oscilloscope and camera but I don’t notice it with my eye. If you are sensitive this may bother you.

 

Runtime & Heat

The i5T Cu is designed to run with 1.301.5V batteries so Alkaline and Ni-Mh batteries primarily. As you know from watching my other reviews I don’t run any light with Alkalines because they leak. Olight has provided the i5T with an Alkaline from the factory, so get it out and replace it with a high quality rechargeable Nickel metal hydride instead. 

For my testing I used an Amazon Basics High Drain cell, Previous testing shows these are slightly above 2500mAh, so basically on par with Eneloop Pro’s for half the cost. Peak output is right at 300 lumens and the light holds this for a timed 3 minutes before stepping down to right at 50% output where it runs for for just short of 2 hours and 30 minutes before stepping down and ran at it’s lowest mode. This time was the FL1 standard of 10% relative output. It eventually turned off completely at 5 hours and 45 min.  There is no Low Voltage protection built in to this light, so my battery had a voltage of 0.9V when I pulled it out. So when the light gets very dim, it’s time to switch the battery. Maximum heat I saw was 30.4C at the 3:30 mark.

I had read a few accounts of people running this light with Lithium Ion batteries so I wanted to test that too. Olight doesn’t recommend this and neither do I after testing. The light isn’t built for this at all, while it does substantially increase the output you will damage the light if you continue to do this due to the immense heat and increased voltage lowering the life of the LED. The light also doesn’t have low voltage protection so I used a protected KeepPower 800mAh cell to protect the battery from damage.

Total runtime with the Liion was 23 minutes to the FL1 standard, 31 minutes till protection kicked in. It’s a pretty linear decline until the 20 minute mark where voltage really starts having an impact on output. Temps are the big story here, this is the hottest light I tested when run this way and that makes sense given this is outside it’s designed mode of operation. Here a bit of a table of time and temps.

 

Time Temp in C Temp in F
0:00:30 36.1 96.98
0:01:00 40.7 105.26
0:03:00 53.4 128.12
0:09:00 69.3 156.74
0:15:00 72.7 162.86

As you can see the light gets dangerously hot, super fast. At 30 seconds it’s 36.1C at 3 minutes it’s 53.4C, at 9 minutes it’s 69.3 C, and at 15 minutes it’s 72.7C. To put this into a frame of reference most adults will have 3rd degree burns after 2 second exposure above 65C. So for this reason alone this light should not be run with Liion batteries it’s unsafe.

 

UI

UI here is super basic as it’s a 2 mode light. The light always comes on in it’s lowest 15 lumen mode and then if you press again you get the higher 300 lumen mode. There are no flashers or anything else. It would have been nice to see another mode to give you an ultra low 1 lumen mode. 


Pro’s 

  • Copper! With a great surface finish
  • Carries Well in the pocket
  • Good beam characteristics for EDC
  • Nice button

 

Con’s

  • Only Cool White is offered to the Public, there are probably better LED choices here too.
  • No moonlight mode
  • Pretty Middle of the road performance here. It would be nice to see 14500 support.

 

Conclusion

The Olight i5T Cu is a nice special edition light for general EDC, especially if you like the patina and characteristics that raw copper can develop over time. Olight’s timing is pretty good too with the positive antimicrobial characteristics of copper.That said you pay the price in weight here for copper, and I wish they would have went with a different LED and a more advanced driver. This is a basic light and it’s low mode is still too high for many who want a 1 lumen or less mode. Other then that it’s a nice high quality light I enjoy having around and I think you will too if you are a fan of raw copper.
