Further Information

I have items with different voltage bulbs, can i just use 1.5v for all? Eg. if i have an item that had a 3.5v bulb previously can i use a 1.5v bulb - will this work? I don't really want to buy all 3 voltages if i dont have to.
Asked by: S
Hello, The issue would be that if the bulb was previously a 3.5V and you placed a bulb rated at 1.5V then the power supply would be too high and the bulb would fail. However if you change the power supply or use a variable power supply then this would be fine.
Answered by: Michael Lockhart

Just to check, if we are using 2xAA batteries to power series and parallel circuits which bulbs are most suitable? Is it the 2.5 V?
Asked by: Liz

Yes this would be fine to use in both series and parallel. You would just likely find that some configuration, such as using more or less bulbs will give different brightness’s.

Answered by: Michael Lockhart

how much power does this use? on a 9v battery how long would one of these take to drain the battery?
Asked by: harry wright

We sell these bulbs in three different voltages, 1.5V, 2.5V and 3.5V and are rated at 200mA. A standard 9V battery can produce between 400-600mAh, as such it would take approximately 2-3 hours before the battery couldn’t power the bulb.
