Hi,

What do you folks think of this:

Well, they say "more than twice as efficient, but don't give
data.

They say "lasts forever" but do not give data.

I wonder what the life of the magnetron/microwave source is? That always
seems to be the limiting factor.

They say "no toxics" but do not tell us what is inside.

Thulium, thallium, dysprosium etc......the usual candidates as found in
CDM/HCI/CDM burners?


They do not give a price.

This is a variation of technology that has been around for
at least 10 years. It makes a great source for projection
systems but, as far as I know, is NOT more efficient in
general lighting applications, and has been very expensive.

I can't say anything about the quality of the lamp based on
the information provided, but they sure have a nice press
release.

I've requested a sample for eval purposes. If, (and I'm not holding my
breath here) I actually get hold of one, I'll stcik it on the integrating
sphere and let the spectrometer take a peek at the output.
