I haven’t actually done anything with it! It was one that I pulled out of a light which I am replacing with an XM-L2 U2 so I figured I would just use it as a practice one. I will get around to seeing how it looks in something I suppose. I really want to do a de-domed XP-G2 in an aspheric host.
Am I right in thinking if I prefer the whiter end of the neutral range I should get something like a 1C tint XP-G2 to de-dome? What sort of tint would that go to after de-dome? Like a 3C or warmer?
Also I used 2K thinners and it took about 30 mins. Didn’t appear to have any effect on the phosphor either.
Someone here has measured color temp before & after - I'm thinking it's got to have been texaspyro - iirc he measured about a 1200-1300K shift downwards. Quite a lot more than everybody would have guessed. For a thrower (and why else would you de-dome?) where color rendering is less important I don't think you can start with one that's too cool. 7000K would give you a de-domed result of 57-5800K or so? Still a lot warmer than typical for a dedicated thrower.
Thanks for your reply DBCstm. I was just able to get $2 worth of gasoline and I think I’m set for many many emitters.
Nice beamshots comfychair, it’s good to see them again. One thing I just wanted to point out was that since the C8 reflector is bigger than that of a P60, they can’t be used for comparing beam angles, right?
You can monitor to see if the dome falls off or is loosened, maybe 2-10 hours, or you can pull it out in 2-4 hours and poke it gently to see if it will easily be pushed/flipped up and off. Lately I've been doing the shorter time (2 hrs), and carefully flipping it off, starting from the side opposite the wires. Overnight takes the guess work out of it. Most of the time now I see a bubble forming under the dome, indicating the dome' seal has been compromised. At that point it comes off pretty easy.
There's no such thing as 'too long', just leave it in until the dome floats off on its own. If you lightly score the dome with a razor just enough to break the outer skin it can happen in as little as 30 minutes.
