The New Super Effecient Incandescent?

I'm not sure how big a pinch of salt is needed here but this is an interesting read from the Telegraph:

You beat me to it Tom.

I heard this promising news this morning on the radio. It makes sense using the same IR technology reflector technology they use on the likes of SOX to reflect IR heat back into the lamp. It makes sence if less heat is escaping and more being bounced back into the lamp the filament wont need as much energy to keep at its operating temp therefore reducing the energy consumption. A typical why didn't anyone else think of this before.

The only "ahh but" I can hear coming is the life span of the lamp. The likes of LED is perceived to last many times longer.

The report reads that LED and Fluorescent is only 14% efficiency. that's a lot, lot less than I though, I was thinking about 35-40%

Its something I'm keen to follow as I'd love to go back to incandescent

LED is indeed now up to 50% efficacy, and fluorescent well above 30%. The journalists hyping up this latest development haven't a clue what they are talking about!

Be interesting to see where (if anywhere) this goes. Read it on the BBC and remember thinking their numbers were duff though.

If memory serves Duro-Test did some experimentation with IR reflective incandescent lamps back in the 70s/80s didn't they?
