It is not safe to run a fluorescent light with a LM465 Lamp Module. Even at 100% On.
The circuitry in the LM465 can react poorly with a fluorescent type load.
If the LM465 is new enough to be soft start. Where it ramps On and Off over a few seconds. The light is also being subjected to a modified AC wave during the ramp time.
An appliance module as mentioned is a better choice.
On the back of the LM465 it should specify incandescent type loads only.
Just had one added thought. If the lamp in question is a Dimmable Type CFL. Then the LM465 may work OK.
I have tried a few Dimmable CFLs with LM465s with varied results. Depending on the model CFL and if the LM465 was a soft start or older style.
