ok cool. the cheapest ones I found were like 70-80 bucks. does that sound right? I read on another forum a while back that u can find them at walmart. the only ones I found at walmart when I looked are par 30. would those work?
The par30 and par38 bulbs that you can buy at walmart of home depot (or similar box stores) don't have the color spectrum needed for coral. They are fine for things like refugiums and scrubbers but not coral health. The cheapest (and highest quality) par38 bulb IMO is the one from RapidLED.
