I wasnāt happy with the rubber boot as it was just a little bit harder to access the tail switch since I put the magnets in.
Much better now, I think thatās about all I can do to this light. Nextā¦ :laughing:
I modded a floodlight by swapping out the original cool white LED with the (supposedly) 90 CRI, 5000k CCT I bought from alibaba for use as an improvised desk lamp.
Modding in action. The original LED (bottom right) is 20w where the new one (wired) is 30w. Iām actually under-driving the one I used for replacement, but thatās okay. 20w is plenty bright for an improvised desk lamp.
Some cactus shot under the modded light. Does this looks like 90 CRI to you?
The LED used for modding. I had 4 of them in my possession. One used in this project, three to go.
Replaced the XHP35 in the Thrunite Catapult V6 with a 3A 5000K 5A 4000K XHP50.2 (12V) to see how the larger emitter would work in a throwy reflector.
From 3 ft - XHP35 Original on Left/Before, XHP50.2 swapped on the Right/After
With the XHP50.2 the beam is wider and slightly less intense as anticipated.
From 50 ft
The effect of the XHP50.2 emitter being larger and HD rather than HI.
Brightness intensity at the hotspot was less because the XHP50.2 is a larger emitter and it definitely no longer throws as far but at medium range is quite bright (perhaps even brighter?). I think I like the results and will probably keep as is.
(Edit - replaced photos with 4000K tint XHP50.2, the first 5000K one had issues on turbo and eventually died
pc-l, on the 50.2 itās a flip chip technology which means it doesnāt have bond wires up top. You can slice the dome off quite close to the phosphor then, in a vertical action, dice the yellow surround off the substrate so only the die surface has phosphor on it, this will virtually eliminate the egg yolk aura and leave you with a pretty tight hot spot and decent-ish beam profile. I just got a new Emisar D1s with XP-L HI and the hot spot is virtually the same size as my sliced/diced/shaved XP-L2 in my older one, same flip chip technology in the XP-L2 as the 50.2.
Thanks Dale, will keep that in mind, I will probably do it step wise, (1) focus emitter, if unhappy with beam, (2) slice and dice. Iāve de-domed once or twice but never intentionally
It really seems a bit worse in the pic than in real life. Doesnāt bother me at all and more importantly no donut hole. Someone should try it with a single emitter.
