Hey all! I've ordered 3, 15 watt COB LED, 6500K, E27 lights for a pendant fitting I'm building. These are for my 90cm tank, I've been using them for a short time on my smaller aquarium and just wanted to see if anyone else uses them and if there are any long term issues they've faced? I haven't had a problem yet and they kick out a lot less heat than my old lights. Thanks for reading!
