Re: VU1 ESL bulbs with HA dimmers?

[nobody@xxxxxxxxxxxx (Dave Houston)]

Well, it's been nearly 50 years since I learned about CRTs but, as I dimly
recall, higher voltages are required for higher delection of the beam so the
bigger the CRT the higher the voltage. Few B&W TVs had large screens so they
had lower voltages. Since these folks are not deflecting a beam, the voltage
is likely to be much less. And, even if they were deflecting a beam, the
"screen" size is much, much smaller than a TV.

I asked Vu1 about the internal voltage and whether the bulbs emit x-rays and
got the following (non)response.

"Detail specifications will be made available after independent and UL lab
testing have completed.  Please refer to our website and blog site for
current updates."

I do not know whether UL will test for x-rays.
