Thanks for the testing, thusfar I just went ahead with a forceps with various results, I have some leds underway that are going to be dedomed, I'll give a few of these methods a try , including the gasoline one (here in Europe I will use petrol instead, hope that works too ).
_the_ - that's a great dedome. Was thinking of trying a different approach for a heat method, viffer750 made it look so easy and I think he quotes a 100% success record, but the success I had with gas, I'll probably stick with it, only go to a high octane - NightCrawl mentioned their gas is 95 octane he used.
I cant remember which worked better, but I also dedomed one using a mixture of gasoline and acetone. Pretty much trial and error, but I never touched the dome or the glue with anything because I didnt want to kill the bond wires.
your led will only work in the uk, if you try to travel with it, it won’t be compatible with batteries and dark environments designed for the rest of the world
Success! I had cut this one down and polished the remaining dome.
Bare emitter Lumen results: 700mA drive current, XM-L T6 1A
Original dome unchanged: 276 lm
Cut down and polished with 2000grit: 200 lm
Gasoline dunk, dome fell off: 264 lm
This one be going in my other HD2010 on copper SinkPad to compare to the XM-L2 T6.
The tint looks slightly greener than before. Definitely warmer now.
Hmm, my vision seems more affected than usual by the emitter at full power. Keep your eyes safe. I need to get some oxy welding glasses…
This stuff is great. It not only protects the phosphor coating after dedoming, but also prevents reflector shorts in situations where an insulating disk cannot be used.
I wonder what chemical in gasoline is doing most of the work. They do sell Xylene in the hardware store. If it doesn't work, then dump it in your gas tank for a slight octane boost.
