Wanted: Old 48" t5 bulbs

[Andrew_B]

I'm looking to test a few bulbs out on my cyps. I don't have much experience with t5s for freshwater so I don't know what spectrums to use. They will be used in conjunction with my 6500k led spotlights. Right now its dual 10000k.

I'm looking to replace one with an actinic or a 14000/15000k bulb of some sort to bring out blues. Let me know if you have anything old from a saltwater tank or something.

Preferably north side for something small like this,
Thanks!
