A Perfect Dedome?

now that’s what I call perseverance!

I could try it, I guess. Good Solvent…

I still think Coke may do it . Just good I had a bunch of extra T6's laying around from upgrades. Got into modding just before th U3's came out, so I ordered a few U2's and before they arrived, the U3's became available, so never ended up using all the U2's.

I'm gonna stick with the gasoline for now - I can live with this method, just hoping the LED lasts a while...

I tried a T6 today, cutting. Tomorrow it goes in the juice to get the rest off. I’ll be putting it on copper and into an HD2010. I want to see if it can take out my XM-L2 HD2010 at 81kcd.

The gasoline xml looks great!

When slicing off the dome isn’t leaving a thin layer (goo?) good to keep air off the phosphor & prevent burning / discoloring?

7

Cool I will have to give this a try. Thanks.

If you have a small ultrasonic cleaner, you might want to try that (at least as a final rinse sort of thing). When I put flammable liquids in my cleaner it is always in a small (like 30cc) cup that is floating in the tank filled with water. The cleaner that I do that in is a small Harbor Freight jewelry sized cleaner. You might need to do a couple of runs with fresh solvent each time.

If its a silicone dome would some kind of silicone spray dissolve it? What dissolves silicone anyways, that is less harsh then gasoline?
I’ve wondered what kind of light output you would get from a concave dome instead of a convex one

Don't know about the phosphor exposure issues - NightCrawl brought up the gas method here: https://budgetlightforum.com/t/-/16982, but didn't mention anything about exposure issues.

11

Heating works fine for me. You need to have the correct temperature and the results may vary..

12

i never expected somoene to try it that pricey pcb

13

Anybody still use Led Seal after dedoming?

14

I think it's the best thing since sliced domes.

I haven't done a before/after lux measurement yet...I'll put it on the schedule. :)

15

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 ).

16

No, petrol only works in great britain. ;)

17

_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.

18

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.

19

acetone works great, you just need to be much more patient than 40 minutes

also, goes faster if you take the silicone off the flat edge around the dome with a razor before soaking

don’t pull it off…it will float off

20

I have to ask. Whats led seal?

21

i wonder if soaking it in goo gone will work too?
goo gone
