Now what would need a blulb this white/yellow for? I have never seen a bulb this low of kelvin burn before. So idk exactly what it looks like but i was wondering what would you need a bulb this color for?
My guess is if your in a coral industry and you want corals to grow fast to sell imo
Anyone else use these bulb or now exactly what they are used for?
