I finally killed one, but the gas didn’t do it. I had the bright idea to try rinsing in acetone instead of iso and even though it was just a quick dunk the phosphor went goofy and peeled up at the corners. LED still works, I managed to get all the phosphor off and now have a dangerously bright XML2 T6 UV emitter on a 16mm Sinkpad. :cowboy_hat_face:
So, don’t do what I did. Rinse in iso only.
this somewhat illustrates why i think solvents other then gas should be tried, i am curious if the gasoline in contact with the phosphor reduces its output at all, if someone did a test between several dedoming methods/solvents i would be very interested in the results
Well, the rule is double the throw (in kcd), and then some little more - so, maybe 105110% increase at throw in kcd. I know guys using other methods get this result Manual Man here: https://budgetlightforum.com/t/-/17492 ). So for example, I’ve done 3 Small Sun T08’s, de-domed in gas. They all go from 95-100 kcd to 200-210 kcd. My results show this same approximate percent increase, so I’m thinking nothing is lost at all, if there is, it’s little. Now with XP-G2’s, I’ve had some disappointing results of not even getting 100, but for some reason it seems like I’m losing amps after de-doming XP-G2’s - maybe they are that much cooler and drives up Vf, dunno.
Hi,
I posted on the “100% dedome” about an XP-G2 I’m trying to dedome in gasoline (see: X-ML de-doming method with 100% success? ). The dome came off easily, but left a thin uneven clear layer of something on the emitter surface.
I’m wondering if there is something about XP-G2s that causes this (different construction)?
