CES 2007: Panasonic displays 'LIFI' - new long lasting non-fading wide gamut bulb

HID (high intensity discharge, which seems to me to fit the description of the lamps we know and hate) lamps have been around a long time.

My guess is they aren't bright enough for pj's or they'd have used them all along.

Panasonic has recently begun manufacturing their own lamps for some of their PJs (DW10000K and D10000K anyway), rather than sourcing them from Ushio. So we may start seeing some interesting developments from them.

"Widespread growth in use of data projectors for meeting rooms, classrooms, churches, and multiple other public venues has placed new demands on projector reliability. Luxim LiFi breakthrough electrodeless lamp technology offers unmatched product dependability, delivering solid illumination over the full life of the projector. Data projectors equipped with Luxim LiFi electrodeless technology deliver maximum value for the consumer."

Sounds to me like microwave heated sulphur gas in a glass bulb. This technology has been proposed for years and produces about half the lumens per watt as a UHP bulb. Thus, for a projector you need about 500 watts of microwave energy, and about 100 watts for a RPTV. I don't like the idea of microwaves beaming at me from my TV. Many people can feel microwaves and animals in tests always retreat from any microwave source. It can damage your central and peripheral nervous systems. There is no way to fully block microwave energy.

At a time where we are starting to move toward LED and laser light sources this technology seems a bit late.

"Luxim LiFi breakthrough electrodeless lamp technology "

I wonder how the electrons get into the envelope.

True. HID bulbs are very high quality and bright bulbs. They are pretty expensive as well which is the reason that they are not used in projectors. They're charging $50,000 to upgrade to HID for the Porsche Cayenne over here.

Nowadays, the high priced vehicles come fitted with HID lamps.

Luxim LiFi seems to be a different technology to HID and a different light source which is more affordable yet durable in the long run.

Microwave excitation is the energy transport.

They are hotter and less power efficient than UHP. So you may not see them as much in FP.

"Microwave excitation is the energy transport."

I'll be darned; that ought to *really* extend life.
