Can you use Red and Blue (6500k 3000k) in same cfl fixture?

Hi i was wondering if you can use both red and blue (6500k and 3000k) bulbs in the same fixture? and if so is there a certain way it needs to be done?

I saw a video of the testing of a quantum badboy t5 8 lamp fixture, in which they had 4 red on one side and four blue on other side. 2red+2red / 2Blue+2blue
but this reflector looked like it had two small ballasts inside it. and i wasnt sure if thats why it was done half and half.
Or if you could put them in say every other bulb? every two bulbs? 2r+2b+2r+2B or 1r,1b,1r,1b,etc so i wasnt sure if other fixtures could run both bulb types at the same time or not.
 
as long as they are the ame wattage there wouldnt be a problem at all, and if you are talkinga bout the banks lights (2' 4' 4 or 8 set tubes) then i have done it to add sup lighting when i wasnt using for somthing else, but mine had two sets of one off switches (making me think it ad two ballasts) and i would run the 24 watt reds in the middle four and 54 watt blue on the outer 2blue 4 red 2blue. and that just keeps it at a level electrical pull so as not to burn out bulbs at an accelerated rate. if you are usingfor veg i can honestly see no reason you would want to use red and if you are using to bloom i hope its only as supplemntary light. if you are talking about cfl single sockets then i wouldnt suggest mixing them on the same fixture at all, but if using tubes go for it but be wary of shortened life spans.
 
i have both in a 2 bulb fixture, i dont know about going 50/50 though? i do know i have read lots about having some 5k-6500 in the budding room but i only use about 1/8 of the off spectrum.. and for prev poster.. im giving that picture a rep bump. sweet :+)
 
Yeah was talking 4-8 lamp or even 2-16 lamp t5 fixtures. such as sun blaze 6 bulb or quantum bad boy 8 bulb fixture.
And Yes it would be just for bloom sup lighting.
like could i just use one 6500k bulb in a 2,4,8 fixture? or sets of two? or one at each end sounds like it would work.
Thanks for the reply.
 
as i stated not so clearly before, if they are not the same WATTAGE then at the very least it would affect the pull off the ballast and because its run on a closed circuit at the very least i would expect it to effect the life of your light negatively but im sure it wouldn't hurt the lumen or spectrum, hope that answered it completely.
