Jetbeam RRT0 Pro - First impressions

LED Flashlights – General Info Other Battery Type Flashlights
1

I received my new 2025 Jetbeam RRT0 Pro this week. My first impressions are as follows:

  • Very similar construction to the 2019 RRT-01 or 2020 RRT-03 with some exceptions:
    • This light does not have infinitely variable brightness. Instead you get 3 modes with the main leds and 4 modes with the colored LEDs.
    • There is no tailcap button so it is a bit like a 2019 RRT-01 or an old Sunwayman M11R.
    • Weight is improved - The 2019 and 2020 models all use a heavy brass pill. The RRT0 Pro is all aluminum. No more brass pill. This makes it feel a bit cheap, but actually makes it more useful since it is less noticeably during EDC pocket carry. It feels much lighter than the 2019 or 2020 models.
    • Battery tube works with included 16340 (with USB C port). I didn’t check if it also works with CR123 as I never use them.
    • Clip is excellent. It’s a ring type clip held in by the screwed tailcap. There is a magnet in the tail. Personally, I think this clip is at least as good and possibly better than the clips in prior Jetbeam magnetic ring lights.
  • Interface could use some improvement. Off → low → med → high → color modes. The problem is it’s too easy to accidentally rotate the ring to the color modes when you just want high. The RRT-03 doesn’t have this problem since you can preset the mode and then use the tailcap switch.
    • I’d have preferred infinitely variable brightness with max being the rightmost position. Colored modes should have been hidden. Or there should have been a much more robust detente between max and colored modes.
  • Beam - Not sure what main LED they used. It’s a round die similar to an SFT-25r cool white low-CRI. The light contains 3 of them in a 20mm triple TIR optic.

Modding the 2025 RRT0 Pro

  • I was dissatisified with the cool white low-CRI main emitters and decided to swap them.
  • The biggest problem was unscrewing the heavily glued bezel.
    • Prior models of RRT-01 and the RRT-03 all had little or no thread locker in the bezel. Jetbeam used quite a bit more threadlocker than I’m used to in this one. It appears to be blue threadlocker but it gripped really tightly.
    • In prior models, there was also a handy place to attach pliers below the bezel, but above the magnetic ring. Not so this new RRT0 Pro. The area below the bezel and above the ring is mostly inset. It is very difficult to grip with pliers.
    • My usual method of using rubber 3M safety walk tape and 2 pairs of plastic pliers didn’t work. It was impossible to get sufficient grip on the part below the bezel but above the ring. I finally decided to just grip the ring and hope the bezel released rather than the body separating under the ring. I used a pair of Smallrig Super Clamps. Fortunately, I lucked out as the bezel did indeed release without affecting the ring.
  • Once the bezel was out, the rest was mostly like any other emiter swap.
    • The star looks like that of the RRT-03. It is a copper star with the 3 leds in a triangle and a multicolor emitter in the center. 5 wires connect the star to the driver through 2 tiny slots in the star. The main emitters are wired in parallel.
    • The only slightly difficult part at this point was reinstalling the star into the light. Getting the 5 wires back through the tiny slots can be tricky. To solve this I soldered pieces of 26 gauge wire to the end of each of the 5 driver wires. I then fed these long guidewires through the slots and used them to pull the driver wires into the correct position. Then I removed the guidewires.
  • I replaced the stock main emitters with three 5000K NTG35 from International Outdoors. This instantly fixed the bad CRI and tint. However, the light isn’t as bright as an FWAA using the same emitters.
  • The battery tube threads are the same as those of the 2019 and 2020 models. The head is interchangeable with tubes from those lights. However, depending on what battery is chosen, there may or may not be enough room to allow the tube to fully close.
  • The driver includes a built-in battery indicator. The colored led lights up for 2 seconds when the battery tube is closed. Green is full. Red is low. I haven’t checked for other colors. Unfortunately this means the stock driver does not work well with the tail switch tubes from the 2020 models as every time you hit the switch you will get a couple of seconds of battery indicator before the main leds activate.

thanks for the writeup, and congrats on the mod :wink:

a 3 mode light with a rotary dial.. like the RRT-03 but lighter

A few other observations:

  • The tailcap is not glued onto the battery tube. This was a refreshing change from the heavy use of threadlocker at the bezel. As such, the clip is removable simply by unscrewing the tailcap then removing the o-ring and lifting off the clip.
  • The clip has a tab that sticks out and slots into the battery tube. This is a nice feature as it keeps the clip aligned. The clip cannot spin when installed.
  • The magnet is glued to the tailcap. I was unable to lever it out, so tried to cook the magnet with my soldering iron. Fortunately, this caused the glue to release and I was able to remove the magnet. However, only do this if you intend to permanently remove the magnet as the heat will damage it.
  • Waterproofing at the bezel after modding seems like it might be questionable. There doesn’t appear to be a clear slot for the o-ring to sit so it tends to slide over the lens. The bezel has just 1 o-ring between the lens and the optic. Unlike prior versions there is no second o-ring between the bezel and head.
  • I didn’t try removing the driver, but I suspect it is probably the same general shape as prior RRT-01 drivers and might be interchangeable with drivers from earlier models. The head appears to use a pill-less construction.
    • This suggests that the RRT0 Pro’s head could possibly be used as a mod host for someone who wants a lighter weight version of the 2019 or 2020 RRT-01 or RRT-03.

The mode spacing is better than in the RRT-03. The low mode is much lower than in the RRT-03. Overall, the modes are well-spaced. However, I would have preferred an infinitely variable setup as there is no moonlight mode.

It’s nice how small and light the RRT0 Pro is. My modded version (emitter swap, magnet removed, Talon grip tap added) weighs 64g with the cell inside and is just 74.1mm long.

Comparing both lights with batteries installed, the RRT0-Pro is noticeably lighter and shorter than a 2012 RRT-01. The RRT0 Pro is also significantly brighter. However, it should have shorter runtime due to the smaller cell.

thank you for all the info youve shared about the 3 mode RRT0 :wink:

Have you confirmed if the stepless rotary driver from an RRT-01 works in the RRT0?

I have not. I don’t have a spare RRT-01 driver laying around.

My guess is the driver is probably the same shape as prior models since the the head is the same size as an RRT-03’s head and the driver retaining plate looks the same.

However, the ring travel exceeds 180 degrees. It turns much more than is needed for an RRT-01 driver. To prevent the ring from turning too much, if you do this mod you should probably also open up the head, remove the ring and then add a new stop to prevent the ring from turning too far.

This could be quite difficult as breaking the glue and getting a grip on the portion of the head above the ring is quite difficult due to the shape of the head between the bezel and ring.

If I had a spare driver and managed to get access to the ring, I’d remove the ring and add a stop to reduce the ring’s maximum travel. I’d make a new stop with a small strip of metal the correct length inserted into the channel for the turn stop below the ring, or possibly fashion a new stop from epoxy putty.

I’d also probably want to fill in the extra detentes for the ball bearing at each mode as those would no longer be needed. Super glue gel would probably work. Or maybe epoxy putty glued in with superglue gel.
