You'll want these light bulbs for every day use in table lamps and in fixtures on high ceilings, outdoors, over stairwells because BLI backs them with a five year full replacement guarantee! Five filament-support wires, and the nitrogen-argon-krypton gas mixture increases the efficiency of the specially treated, heavy-duty tungsten filament.
The first light bulbs did not burn out. That's a fact. There are antique light bulbs that have been in use since day one. Now we all know about the light bulbs you can buy in the store now. They burn out very fast for the most part. Now why is this? Maybe because after they figured out that the thing was going to last for ever, they realized there wouldn't be much money in it in the long run. You can now buy these exclusive lifetime light bulbs through BLI and not have to change bulbs every time you trun around.
