What did you mod today?

Nice mod djozz and a nice improvement in output to boot. :+1:

Some brass goodness today. Another upgrade to the CRX 18350 brass triple Nichia.

I installed a new brass & 14mm glass topped switch cover with green tritium vial.
Previously the light had a rubber boot.

Length - 72 mm
Width - 22 mm
Weight - 104g (with cell)
Max around ā€“ 2100lm OTFAluminium jacket.

You are to much CRX. :beer:

I wasnā€™t 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 thatā€™s about all I can do to this light. Nextā€¦ :laughing:

Hereā€™s mine, far beyond CRXā€™s mod :smiley:

I just can do a LED swap on Novatac 120T :partying_face:

:slight_smile:

Cool, looks brighter. Did you have to file an MCPCB into a cross shape or use another method?

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. Iā€™m actually under-driving the one I used for replacement, but thatā€™s 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.

Installed LD-A4 driver (3A version) in Jaxman E3 219C 4000K.

Album with pictures

Iā€™m using normal 16-17mm MCPCB and solder short wires to the driver contact.

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 :frowning:

Dedome the emitters. You will see a large difference doing so.

Good suggestion BlueSwordM. thatā€™s definitely next on the list of mods to consider.

My current mod/tweak is to get the emitter dialed in. Other users indicate that de-doming worsens tint-shift which is something Iā€™d like to avoid.

pc-l, on the 50.2 itā€™s a flip chip technology which means it doesnā€™t 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. :wink:

Virence quad board
$0.18 faceted reflector from ebay
Nanjq 105D flashed with gChart ramping UI

Nice! I like the look of that :slight_smile:

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. Iā€™ve de-domed once or twice but never intentionally :open_mouth:

Staticx57, got beam shots of that lovely facet?

Can you give us link for the reflector?

Itā€™s no LEDiL boom but it works with the E21As

It really seems a bit worse in the pic than in real life. Doesnā€™t bother me at all and more importantly no donut hole. Someone should try it with a single emitter.
