GE LED Light Bulb (22622 / LED115ED28/740)

Works well in a Altman Scoop 154 for our work lights in a theatre setting, replacing 1000w halogen lamps -- so significant power savings. Had to separately purchase a EX39 base extender to make it thread properly in the scoop. Though non-dimmable, it can actually start to dim somewhat at around 20% intensity before it flickers when going down beyond that. You can hear the fan, but since we're using it as a work light, it doesn't bother us that much.
