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

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

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

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

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

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.

The life of the Fusion Lighting sulfur lamp system was
always limited by the life of the magnetron. I don't want
to quote an incorrect number, so all I will say is that my
recollection was that the life of the magnetron was
significantly less than 10,000 hours.

This lamp may use sulfur. I'll have to check further.

Indeed. I always reckoned on 8000hrs with the multiple commercial magnetron
units Fusion used.

I do hope so. The spectral output of the Fusion lamp was excellent despite
the poor system efficacy..

Vic,

My recollectionof th elife of the sulfur lamp system (10,000 hours dues
to magnetron)confirms yours FWIW.

gaah! Obviously the linkage between my brain and fingers wasn't fully
awake when I wrote that! (The typing, I mean... the context is true...sigh)

The shorter life of the microwave driver compared to the lamp capslule is
what I remember too. As for color, the sulphur lamps demonstrated in
installations at the DOE Building and Air/Space Museum in Washington, DC
were O.K. from the color rendering standpoint; but they were above the black
body curve and the light had a greenish cast.
