Maybe slightly O/T, sorry. I have a big "STOP" tallight that I want to rig up as a shop sign. It has an 1156 two opposed pin socket and I've got 120 AC to DC that go up to 1 amp. But an 1156 pulls 2.1 amps. Anyone know of a bulb number that will fit but be of low enough amperage? I know LED's are low power, but I'd rather use a "real" bulb".
(whips out his handy 1968 Allied electronics catalog) (whips out his handy reading glasses) Ok, he uses google instead http://www.bulbtown.com/Single_Contact_SC_Bayonet_Base_BA15S_s/326.htm
Yea, a 1156 bulb is rated at around 26 watts which works out to just over 2 amps. Try a JC-4010, it is a halogen bulb with the correct base rated at 10 watts.
fROM THE sQUIRREL'S LIST, this is a real common bulb. 1/2 as bright as the 1156. #93 MINIATURE BULB BA15S BASE - 12.8 Volt 1.04 Amp S8 Single Contact (BA15S) Bayonet Base, 15 MSCP C-6 Filament Design. 700 Average Rated Hours, 2" Maximum Average Overall Length
yep , i guess that's right , i should have checked first before posting P= I x E , so 26 watts divided by 12 volts equals 2.1 amps
