LF: Used 150watt de bulb
 

I'm looking to try out some different color temperatures on my HQI. If anybody has any old bulbs that they are going to toss, I'll take it. Thanks.

The problem with comparing used bulbs is that the spectrum has more than likely changed and won't give you a good comparison.

I thought so. I guess I'll just go ahead and pick up a 20K bulb and hope my corals look better than 14K. Thanks anyways.

i have a month old ushio 20K for cheap if you are interested
