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.
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.
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.
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.
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.
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.
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.
