I tried to operate a Halogene lamp(110V Bulb) and a Fluorescent fixture(40 Watts) with my old LM465.
All run Fine !!! (no heat).

But why does its not recommanded to install these fixtures on LM465 ?

The LM465 is a dimable light module and shouldn't be used on a fluorescent light (transformer inside). Also allot of halogene lights have transformers in them which can't be dimmed by the module.

I don't know if anyone has tested the LM465 on these types of lights if the module is set to full (100% bright) and left there long term.

Inadvertently dimming a Lamp Module connected to a transformer or ballast could cause these components to overheat.



Yesterday it worked.
Today it doesn't work.
X10 on Windows is like that.

If the halogene light is 120 volt filament and not a transformer type. The LM465 should have no problems. Two wire Wall Switches; that dim and not a relay type; steal power through the light could in some situations have a problem. Due to the lights higher resistance.
Fluorescent with a older ballast or a low voltage transformer light could damage the Lamp Module or the light itself. New electronic ballasts are no better with dimming modules.

Now dimable CFLs that I have tried will work in the lamp module but not wall switches. I also found the plain X10 Lamp Module worked much better than a fancy one with a slow ramp up and down with dimming CFLs.

Scuse me I don't understand few words (I'm french), I am ignorant sometimes !

When you write CFLs, what do you mean ?

Compact Fluorescent Light Bulb. Energy saving type bulb. I use them all over the house. Like a 13Watt is about the same light as a 60 Watt regular incandescent light. Many are a spiral tube like a cork screw and screw into the standard light socket.
No not ignorant. Many of my work customers are from other countries and clarifying things is no problem.
