[shockwave00]

Hi All,
I have 4 power compact lights all of them are white when they are off.. 2 make my water light up blue. I need to replace one of them. They are 65W and I'm not sure if they are white 10K or acnitic or what? Please help and tell me what I have!
THANKS

the ones that come up blue are actnics and the others are your daylight if you need to replace the blue and want it the same you might want to go to your LFS with the bulb so they can tell you what type it s 420 or 460 0r 03 actnic. But donot but it there they can be very pricey at a LFS if you can wait order it online

I reread your ? im kind of confused now

are you not sure what type actnic you need or your unsure what the lamp is that is burned out daylight or actnic well in most 4 lamp PC fixtures(if thats what you have) theres 2 daylight lamps and 2 actnic lamps and are normally across from one another so for example the 2 blues are in the back and only one daylight comes on in front the other is also a daylight now I suggest taking the lamp again to the LFS for the correct type very hard to answer without pictures and even then very hard to get right
