I know I know…we are talking about 80 to 150w and even more than 200w for 10klumens ! Cpu cooler are much more bigger and feature fan designs…
I was talking with Dale from Haikelite about fan cooling for the big 3xxhp70.2 lights
But considering the current thread I would like to see the small light with exact time specs. For example a 3000lm light should sustain it for 5min mini. Like tig welder are rated with running coefficients…
The decent/honest manufacturers often list a estimated time until stepdown + output after stepdown on their FL1 runtime charts. Even the FL1 standard has it’s own issues though, like how Maglite games it to massively inflate their runtime numbers without making any mention of the huge stepdowns.
Oh wow!!!
FYI 1st thing I did after turning the light on was configure the Thermal limit and calibrate the temp sensors. Set the limit to 40C. By default it’s set to 45 I think and it thought the ambient temp was sub 15C (room temp around 22C).
I could see how it could cook itself at default settings… Good thing I like messing with settings lol
Also, another thing I noticed is that the temp sensor doesn’t update the readings often enough for this light.
Toykeeper mentioned that it updates every 6-7 seconds, which is fine for running Turbo from a “cold” start. But if you turn it back to turbo after it steps down, it will stay at turbo for at least 6-7 seconds before it starts stepping down gradually again, rinse repeat and now you have a dead light…
This light needs a temp sensor that is more “realtime” that updates every second and more aggressively steps down depending on how much over the limit it is
For that reason I decide to order SST40 variant of Nightwatch with 5k lumens because want turbo for longer times and its have better heat dissipation design compared to FW21Pro.
I have a stock FW21 Pro. Does anyone know what the color temp is with the XHP50.2 emitters in this? 5000k? Or 6500k?
The color temp is ok for me, but my only quibble with the XHP50.2 is the green corona around the hotspot is a little irksome, though it isn’t terribly bothersome - generally only noticeable when white wall hunting. But I do appreciate minor improvements, when I can get them.
Is there another emitter option, to mod this light with, to get rid of the green corona, but still retain reasonably high, cool white, lumen levels? Would XP-L emitters work well in place of the XHP50.2 emitters?
I don’t care if I can’t hit 10,000 lumens on turbo. For the most part, I would use the light within the ramp range, only using turbo very briefly on occasion.
Probably 6500K is original FW21Pro emitters. 5000K version of XHP50.2 are difficult to find and manufactured only by special order. Good replacement for XHP50.2 is SST40.
