Have a new light over dining room table with 3 retro-style led bulbs, but their resistance isn’t enough to make them turn off when the light switch goes off. Can I wire a resistor into the switched live for them to increase the resistance and hence make them turn off? If not, what is the recommended approach (apart from trying with other bulbs, which I’ll look at but have little hope of success).
The LED bulbs must be dimmable to work with Lightwaverf switches. Even when the switches are ‘off’ there is a small trickle current through the switch to allow it to extract power for the receiver. This is enough to turn on non-dimmable bulbs. Even then not all dimmable bulbs work well.
You can’t put a resistor in series with the bulbs. Where a resistor can be used is to help with some situations where the total load is below the minimum. A special 10W ballast resistor can then be used in parallel with the bulbs to provide the minimum load.
they are dimmable. think a ballast resistor is the way to go but they’re costly for what they are so will try other bulbs too…..
Use the switch to drive a relay, unless you are using a dimmer switch.
