I'm selling these because I did not like the pinkish hue they gave off. They have been used a total of 60 hours. I think the shallow depth of my tank made the pinkish hue more predominate...just speculating, but I didn't like them. Anyway, $32.00 shipped anywhere with-in the continental US.
PM me!!!
I am using these bulbs on my 20-gal long and 29-gal. Like you've said, my 20-gal long looks more pinkish and I think it's likely more apparent because of its shallow depth. The 29-gal actually looks pleasant; not pinkish at all. It is also higher.
I don't notice the pink hue at all on my 75g. However, 5000K & 6700k lamps make the tank look very green to me. Maybe I am a bit more color blind in the reds. I used to have a hard time with my Seachem NO3 kit so maybe that explains it
