#1383 bulbs are one of two popular styles of elevator bulbs. These two types vary by the base type (required by different sockets) -- either single or double bayonet base. The #1383 elevator bulb has a single bayonet base, also called a BA15s base.
Traditionally these have been incandescent bulbs running, as the ones we carry, at around 20 watts. And while elevators vary in how many bulbs they use, we've seen some with 5 or 6 ... we seen others with 12 to 20 bulbs. With elevators running their lights 24 hours a day, that can total up to a lot of energy being used!
For instance, if an elevator uses a 3 x 3 design of light bulbs (nine total lamps), then it's using 180 watts per hour, or more than 4 kWh at a cost of around 50 cents per day and $180/year!
But put a #1383 bulb LED replacement to work and you're suddenly operating on just 3 watts per bulb and slashing over $150 a year off that electric bill, more than paying for all those lamps compared with buying incandescents. And of course their lifespan is so much longer than incandescent bulbs, which puts the bother of maintenance / replacements to the back of the mind.
