WTB: Jetbeam RRT01 – Any place to buy it?! + [RRT01 2019 discussion]

thats a Lot of Lumens! maybe someone else can report the unmodified output.

2012 Original RRT-01, on my meter
sw45k
260 lumens

stock xml
390 lumens

the sw45k is 33% less bright than the stock xml, and I Love it!

Low Lumens need love as much as phat chicks do.

Another interesting thing I noticed is the XP-L version of the new model apparently comes with a smooth reflector and Nichia this Light OP model. Nice that they created both if they are willing to sell parts down the road.

besides the texture,
is there also a difference in bottom hole size,
and do they use different centering rings

inquiring minds like pictures… LOL
thanks for all the info shared :beer:

One thing that surprised me - the neutral white RRT-01 and RRT03 supposedly both use Nichia emitters, but they are very clearly from different bins:

  • RRT-01 2020 neutral white: very warm color temp. Maybe 3500 or 4000K. Low CRI. Slightly greenish at lower power. Really not that great.
  • RRT-03 neutral tint: cooler color temp than RRT-01. Maybe 4500K. Rosy tint. Rosier than any of my XPL HI Leds. Reminds me a lot of the rosy-tinted Nichia 219B. The stock RRT-03 emitters are superb. Possibly the best color temperature and tint of any light I own.

I don’t have the capability to measure CRI, but it seems a lot better than in the RRT-01. The overall beam pattern looks much better than my high-CRI SST-20 lights (even the good tint bin ones in the FW3A), but reds still don’t pop as much as with the SST-20.

The 219C sm403 that I’ve had have varied greatly between even different examples of the exact same light (bought a bunch of IYP07s for gifts). Some have been nice and rosy with a slightly cooler, maybe 4200Kish? temp while others are greenish at everything but high modes and are a bit warmer. Lower R9 vs SST-20 4000K sounds consistent with that too.

i kept wondering why you guys were talking op reflector. i have smooth reflector because they sent me an xpl (Even though i had asked for nichia) .

now i’d like to compare op vs smooth. i know the theoretical differences. contractor, your shots were with op yes? mine were smooth…

The orange peel is very light so it’s probably only ~15% less throwy with the hot spot to corona transition being less defined and more smoothed out. The spill is more “even” edge to edge where as SMO kind of fades out more and more as it reaches the edge.


My 2019 is with smooth reflector and 219B. I fixed the focus a bit better by using 3 layers of kapton tape under the reflector very carefully cut and ditched the centering ring. YMMV.

My 2020 originally had Nichia so it has a light OP reflector. I don’t have the 2020 model in smooth/xpl version to compare.

Now that I have changed the emitter and sliced it I doubt the comparison is of any use. Too many variables.

Dont forget TIR blends the more desirable part (the front) of the beam MUCH better and SMO reflector especially brings out the worst in most LEDs.

agree!

caveat, the tradeoff for enjoying a larger hotspot, is larger battery drain

assume the center of each beam is at the same brightness:

However if that pic was comparing the same emitter in the same model of light, it means the one on the right would be a larger - and therefore very likely more efficient emitter - too.

For example, between my SC64 LE and H600c, the 600c matches the LE in throw at every submode but has a significantly wider hotspot and brighter spill. AFAIK the current draw at each submode is very similar between all current gen Zebras (based on comparing runtimes for different models).

Can anyone w stock nichia single and/ or triple post a couple beam shots? Preferably versus something nice. Would like to see what could’ve been…. and doesn’t rrt03 have secondaries? Any unbiased pics? (Not from the company’s marketing dept)

IYP07 on left, RRT01 on right. Both stock emitters - 219C 4000K 9050 vs 7000? Set to mid mode which is ~40lm on the 07 IIRC, and tried to match it with the RRT01. Wall in the second pic is stark white.

wider beam angle, lower Lux
(wide looks dimmer than narrow)

.

the test contactcr did of the 219c 4000k shows
RaR9 of 70(–27)… the (R9) is negative,
the duv of 0.0040 is greener than sunlight, whose duv is 0.0032

.

he has modded it to LH351d 5000k 9050, dedomed made it 4500k and duv dropped pretty much exactly onto the incandescent BBL.

.

congrats!
great to hear the 2020 has a good beam and a nice LED now

wondering if the thickness of the centering ring might be the secret to a good beam

new question
Are the primary LEDs in the RRT-03, the same low CRI 4000k 219C as in the 2020 RRT-01?

Yeah the R9 is clearly lacking but threw that white wall shot in to show that it’s also going greenish on lower levels. It does clear up a bit with higher output but like contactcr said, the hotspot itself it still more yellow/greenish.

If you can reflow ill send you a shaved LH351D to put in it.

I really appreciate the offer :laughing: but I’m probably planning to sell it since the UI just wasn’t for me and don’t want to mod it before that (I’ve killed cheap lights by being clumsy and am leary of selling only passable mods to someone else). Also to fund another rotary purchase I was finally convinced to take the jump on…

Uh oh… if you haven’t been talked out of it make sure you get hi cri option if your jumping in that deep. Then tell me how much you like (cause i don’t have) Taking loose survey. But we never know, til we know… do we?

Contactor- why do you like the Samsung (lh351d) over the nichia b? If i had a second one ready I’d be asking for it.

Bpd, thanks for the pics, I’m not talking trash, just being a smart ass for the reformed…

That penlight (is that what it is? Looks nice snd rosy next to that aberration nichia. Some of my favs are 219c. When they’re good, they’re great huh?

Oh I did haha, that run getting low before they switched to 5000K helped make my decision.

Personally the biggest benefit of LH351D/C (and good bins of SST-20) is just being able to safely use them in basically any light, with any driver and having an easy supply. Efficiency isn’t really that much better when sliced and/or used with the minus green filter but there can be some advantage there.

Haha! Thanks. I want a full report, cause I’m gonna miss out unless later on secondhand market! And having extra slash will help!
