Removing 10V dimmer from bank of 2D CFLs

nolly1953 · May 22, 2018

We have a set of Thorn 2D CFLs controlled by a 10V dimmer switch. We no longer require the dimming function so, by disconnecting the 2 x 10V connections from the variable resistor, the lights are operating at maximum brightness.
Just checking is it okay to leave these 2 leads disconnected, or should I really put a fixed resistor between the terminals.

Are you sure that they are CFL, normally a rotary analogue dimmer switch is for LED? There is usually an on/off switch with the dimmer switch next to it. Is that what you mean?

Vortigern, thanks for your reply.
Yes. See image. These are used throughout the church building. The dimming facility is no longer used. Also as units fail we are fitting LED retro fit units which cannot be dimmed so it makes sense to remove the dimming facility. Yes there is an on/off switch with the dimmer switch next to it. At the moment I have disconnected the dimmer and all seems to work well. I suspect that dimming the CFLs shortens their life which is another good reason.
