FAQ

What is the difference between a Ba15d and a Ba15s base?

The ‘d’ in Ba15d stands for ‘double contact’, meaning there are two electrical contacts at the bottom of the base, typically for positive and negative connections. The ‘s’ in Ba15s stands for ‘single contact’, with only one contact at the bottom, where the metal casing itself serves as the other contact (ground).

Can these 24V lamps be used with both AC and DC power sources?

Yes, as incandescent filament lamps, they are purely resistive loads and will function correctly on both 24V AC and 24V DC power without any issue.

What is the typical lifespan of these incandescent signal lamps?

The lifespan of industrial incandescent lamps like these is typically rated in thousands of hours, often ranging from 1,000 to 5,000 hours, depending on operating conditions such as voltage stability and vibration.
