A bulb that you will find very similar to the Chroma 50 is the Philips Colortone 50. I purchased mine thru a local lighting store. I've also read that the Philips bulb is a better bulb than the GE Chroma. I have the GE Plant & Aquarium bulb and that is definitely a "pink" bulb. If you look at the Chroma 50 and the P&A bulb, lit, side-by-side, you'll see what I mean. Yes, I do have the GE Chroma-50 also.
