FAQ

Question?

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 two separate circuits or polarities. The ‘S’ in BA15S stands for ‘Single Contact’, with only one contact point at the bottom.

Question?

Can I use this 260V bulb in a 230V or 240V system?

Yes, you can. Using a bulb with a higher voltage rating on a lower voltage supply is safe. It will result in a slightly lower light output and color temperature, but it will significantly increase the operational lifespan of the bulb.

Question?

Are these bulbs suitable for high-vibration environments?

As standard incandescent lamps, the filament can be sensitive to heavy and continuous vibration, which may shorten their lifespan. For extreme vibration applications, considering a modern LED equivalent with a BA15D base is recommended for enhanced durability.
