Guy from work got one of these. https://www.milwaukeetool.com/Products/Lighting/Handheld-Lights/2354-20

Wondering if anyone has checked to see what emitters are being used.

One xpl-hi for the spot, and 4 xpl2 emitters for the flood. About 4000k, good color rendition, probably 80 CRI. I measured about 120kcd and 700 lumens for the spot light alone. Biggest negative for me is the cheap plastic lens. Overall a great design, and good value if you already have Milwaukee batteries.

“I just purchased a couple of these with hopes to modify by replacing the existing white LEDs to a pure 365nm UV led and also install a glass lens instead of the plastic one it comes with. Is it possible and has anyone done it with this model?

I have so many battery operated Milwaukee tools That I have all these different batteries ranging from 18v 2amp hours to the 18-Volt Lithium-Ion High Output 12.0Ah battery So that’s my main reason for wanting to modify this light. If successful I eventually want to modify another light which has dual power it is can operates on ac or 18v battery and produces 3k lumin in flood mode.

Anyway I have taken the 2354 apart and since I thought it was just a matter of just swapping out the led’s and have since learned it ain’t that simple!!

I have no electronic background But I can solder so what do I need to do next to figure out what size 365nm UV led I can use?

The specs on the light says it produces 1200 lumin in flood mode using 4 leds and 600 lumin in spot mode using a single led in the center.

Please help! Here is a photo of the light

It looks like the 4 peripheral leds are mounted on a mvery custom mcpcb, with the center led being on a proprietary aluminum mcpcb. I doubt you’ll be able to find an aftermarket one with an led mounted, so reflowing the uv emitter on it is your best option.

These are 3030 size leds, so any xp-l uv emitter will work in their place. You might want to check the current requirements for the uv emitters before tackling this since a driver swap might be needed to drive everything properly.

Reflowing is not difficult. You need solder paste, a way to apply indirect heat to the mcpcb and fine tweezers.
