This light fixture replaced a couple of 48" fluorescent lights and the difference is absolutely amazing. These are in an unfinished portion of our basement that has 9' ceilings and instead of folding the LED wings complete horizontal, we found we obtained the best light coverage and the least amount of shadowing by keeping them almost completely vertical. Be sure you play around with the angle of each LED wing to obtain the best coverage for your particular situation. Couldn't be more happy with our purchase. Installation was as easy as replacing a standard light bulb. Just screw it in and flip the switch. Easy as pie. Overall great buy and I highly recommend.
