Re: VU1 ESL bulbs with HA dimmers?

[nobody@xxxxxxxxxxxx (Dave Houston)]

I think that was only for color TVs where the voltage is 32,000 volts.
Radiation increases with the voltage. It's not likely that these lights will
have anywhere near that voltage - not if they are going to fit existing
fixtures.
