Thanks , that’s what I was thinking as far as the manufacturers claims of same output as a 100 watt incandescent . I need to check the specs on the bulb packages . I used to keep a large saltwater reef 25 to 30 years ago . And we were always trying to maximize our lights , both lumens and spectrum . Haven’t done salt in a long time , but did have the 180 set up as a fish only cichlids tank for 20 years . When I decided to set it back up after a move I decided to go to a low tech planted freshwater . I didn’t really read much and rebuilt my hood with 15 E27 sockets for LED floodlights . There are so many good bulbs available , daylight spectrum , grow light spectrum , blue , red , etc . I figured I would blend multiple bulbs and more light was better . Now tha I’ve read more , I realize I’ve way overdone my lights and was headed toward an algae farm . I don’t know how to post a photo but the light looks spectacular . I am almost thinking of going fish only .
