converting a Q5 to High CRI Q5

[importculture]

First a little background. I usually buy lights in bulk especially lights that I like. I then sort them by color temp and use the worst color temp ones first. I also like to modify or polish the worst color temp ones usually cause I don't mind if they get damaged or break. That being said. I bought 7 Jet I I.B.S pro's when they came out. Two of them ended up having a really pinkish purple color temp. I gave one to an aunt and have been using the other since I got them. I noticed that there wasn't much spill from the jet I pro's so I was using it with the head removed. Well, the LED is recessed in the housing where the head screws on so the flood wasn't that great either. So the other day I decided to cut slots in the threading to increase the flood size. After I was done I cleaned the light and used alcohol on the inside where the emitter sits. Well when I took a cotton swab to the emitter the dome came off. I thought I just broke a seventy dollar light. Well I put in a battery and to my surprise it still worked. So I took the cotton swab and cleaned off the rest of the rubber cement or whatever that was used to glue the dome to the LED. To my surprise when I put the head back on the beam was incredably warm. I compared it to my other jetbeam's and my warmest L4. I don't have anything with a beam this warm besides incan lights.

So I also have a few questions. Has anyone else done this and ended up with the same results? Is it really the dome that filters the light emitted to be the off color temps we have? Does the LED need protection from moisture etc or is the bare emitter (by this I mean the emitter without the dome and silicone)already protected? If it needs protection what kind/brand of epoxy should be used? If this is no coincidence I have a few lights that's getting this modification. Thanks for any advice or help.

The bare emitter(lust the die and phosphor) is already protected from the environment with the dome and the metal ring. Under the glass dome is silicon something.

Removing the dome does seem to make the lights warmer. It also decreases output and might greatly decrease the life of the phosphor.

Cree makes warmer LEDs than you have.
