"Dollar Tree $1 Greenlite LED Bulb 9w (60w) Review and teardown"
Today, my wife picked up five Greenlite 75w bulbs, five Sunbeam 60w bulbs
and two Sunbeam 90w flood lights (large).. (She loves a bargain)!
I've installed (2) 90w floods, (4) 75w and none of the 60w.
All 12 bulbs were pre-tested for a few seconds and they work..
I'm running one of the 90w floods outdoors (motion sensor light) and it seems to be as bright as the incandesent was!
I have the other 90w lighting up my office (temporarily as a test).
It's a tad too bight in here..
These bulbs appear to be good quality. If any fail, I'll post an update..
