How to know what Kelvin?
I purchased a MH retrofit kit.... Its 2 DE 250w HQI... with 2 T5 HO actinic... I didn't know which kelvin rating to get so I found some used on Ebay to try... they are Odyssea 150000K.. I hooked them up and they are really white.... even with the HO bulbs.... I really see no blue tint at all... This is over a 90 gallon with ballasts from hellolights ARO.....
I was wondering if there is a way to tell if these are actually 15K? there is no writing on the bbulbs.....you never know what you get from ebay but they were very cheap ($20 for 4) so I just got them to try before spending alot on something I didn't like... I like a bluer tint to the tank.... how do you tell? how can I know what I will like without actually seeing it... thanks !!

Do you have picture without HO on? Usually 10000 K is more on the Daylight/yellow, 12000-15000 K are on the cool white/some what blue and 20000 K such as the radium bulbs are really blue.
if your bulb said what it is 15000 K, it should be on the blue side, but than, $20 for 4 bulbs, data could be misleading. Best
