Rofis TR20 Angle Head Tube Light Review * 11.15.16 PIC HEAVY*

Hey everybody,

I got this little Rofis tube light in, the TR20, and it’s really a nice option on an old idea. Rofis TR20

The 18650 tube light with a twist, literally, the head rotates to hold a 90º angle. They’ve done a really nice job implementing this, as a new light the action is quite stiff and will absolutely stay in place without question. Regulated circuitry, double e-switch side switches with illumination indicators for above 50% charge and below 50% and a flashing red low voltage warning. Comes with a high capacity cell. Nice touch. This is a Rofis branded 3400mAh cell labeled 3.6V and 12.24Wh. It’s protected and on the long side, I’ll have to get some measurements and double/triple check fitment of other cells in the light, but I don’t see a real problem as the spring is quite compressed with this long cell by the feel of it when putting the tail cap on.

I’ve got a BLF coupon and link to insert here, which I’ll do directly (I’m behind, wanted to get this started… Smile )

A BLF Group Buy is also offered as an introduction to this light, found in the group buy thread here in the forum…BLF Group Buy Rofis TR20

The review light has an XP-L HI with an approx 5000K tint. It comes with a nice blackened SS deep carry pocket clip (head is held above the clip for the angle to work) It has a strong magnet at the tail which is externally removable, they did this by putting an 1/4”×20 socket in the tail of the light and threading on the magnet for easy removable at will. Another nice design feature. Wink

Fit and finish are very well executed, no chips or mismatched ano, this has all the apperance of a very high quality light. Ano surface is not quite the matte satin of some, but not shiny or smooth either. A nice balance with good flat topped knurling. It does take some effort to rotate the head, very very snug.

I’ve taken some preliminary output readings to get started, have to get pics and get them in here asap.

USB charging built in, I put my clamp meter on the cord and it showed a very safe (but slow) 0.29A charge rate.

5 primary modes, moon is available as a press and hold option from off…

0.03A for 11.01 lumens
0.06A for 24.81
0.15A for 81.42
0.41A for 219.08
1.30A for 560.28
3.00A for 948.75 lumens

I’ll get some pics and try to break down the light so y’all can see how it’s put together, wanted to get this rolling as I’m already enough behind and scrambling…

To be continued…

Ok, so, as much as I was liking the little angle head Rofis TR20, I no longer have one. Sad Bella was cracking the whip so I got busy and took pictures which of course meant I wanted to show you guys EVERYTHING!

So, all in all a very nice light indeed. BUT, the bezel is glued onto the head and the battery tube is glued into the head from the other end. I found the rotating head to be assembled too tight, making it difficult to change, but leaving it in the angled position was suiting me fine as it fit the nice holster very well this way. The big o-ring between the angles had it sealed well, without a doubt, and the spring loaded ball detent stop also functions perfectly. The UI is nice, feature set is high end with the active voltage warnings and such. All in all, a very well made light. The copper mcpcb is truly DTP, but very little thermal paste was used in installing it such that the majority of the copper mcpcb was not making contact with the nicely machined emitter shelf. Still, very few minor issues, well done Rofis. Wink

Hoping you break this light down soon so I can see inside the head (or should it be “heads”?). Nothing wrong with an XP-L HI in a tube light, but in this case with the rotating head and the magnet, this light is just screaming to be used for close-to-medium range work where I’d want something floodier, with a less pronounced hotspot.

Based on the geometry of the head, I am picturing a basically semicircular MCPCB with the emitter right up against the flat side, and the reflector having plenty of clearance on one side but being flush up against the wall of the light on the other. So cramming a triple in here would mean, at a minimum, coming up with a spacer with the exact diagonal half-cylinder shape to fit properly.

Very tempting, but i already have a triple JR10 with 22mm electronic switch MTN driver, 18500 cell and magnetic tail.

Still thinking about this one though due to the charging option.

Here's a picture of the inside of the older models head, don't know if it will be the same design or not...

My TR20 was a piece of junk . the head would not adjust. The seller, Gearbest has not been much help.
I love my JR 20 Rofis and carry it every day. The Rofis people stepped in to help me by promising to send me a replacement light handpicked off the assembly line

They are all hard too move you have to fiddle with it. It takes a while but gets easier. Id rather have it hard to move then easy because then it wont stay in place.

Cool, thanks for the teardown pictures! I guess the emitter isn’t as far down in the head as I thought.

What are the dimensions of the reflector? And does it seem like in theory one could drill a hole through the center of the emitter shelf and reach the wires through?

The reflector is 19mm in diameter by 14.3mm in height.

The wires come through on the side, a wide oval hole, after exiting the SS pivot bolt. Bring em through the center, like for a triple? Possibly, but the driver assembly is not easy to get out without damaging it. Not sure it’s pushing enough power for a triple if that’s what you’re thinking.

Thanks. Yeah, a triple is what I was vaguely thinking. Might do an emitter swap and/or try to find a TIR that fits. The beam profile is the only part of this light that I’m not really fond of.

A triple is fairly easy, the heatsink just requires a bit more work, hole in the centre and groove in the bottom. Very unlikely to get the driver out intact. I had to push mine out through the switch hole, it did not survive.

It really does appear to be a quality made light, the stainless steel backer insert for the switch boots fits in snug and solidly supports the boots, puts decent pressure on the silicone flange inside to prevent water intrusion. The SS pivot bolt is apparently glued in place, I got it to loosen slightly and make the head somewhat easier to operate, but in the end I killed the bolt to get the two pieces of the head apart.

It’s not made to be disassembled, for certain!

To put in a triple mcpcb it would most likely be far easier to bring the wires in from the side and cut a groove for them in the side of the mcpcb, that’s probably what I’d do, but since the driver is not accessible to power up the 3 emitters I probably wouldn’t go that route.

There are wide angle TIR optics that have a honeycomb pattern on the surface, I think one of those might be the ticket if you can find one with the right dimensions. Failing that, simply put some DC Fix on the lens and call it a day.
