White LED lies: It's great, but Nobel physics prize-winning great?

And we're also seeing plenty of snake oil - "It's LED therefore it's green".

There are several LED luminaires that are actually considerably less efficacious than the 'equivalent' tungsten-halogen luminaire - in some cases less than a basic tungsten!

One LED fixture I've recently seen is only 9-10 lm/W - while the 'similar' tungsten-halogen is 13 lm/W

Won't name names but they're easy to spot - if the fixture spec only says how many watts of LEDs it has and doesn't give both the input power and beam lumens, you can be pretty sure it's better at heating than lighting.
