Why aren’t High Pressure Sodium (HPS) lamps being considered as an alternative to Incandescent?
Here’s a link to a page where they are sold:
http://www.4hydroponics.com/lighting/sodiumbulbs.asp
Here’s a competitor’s link so I’m not accused of playing favorites:

I use them in my greenhouse to artificially lengthen daytime when needed.
They’re twice as efficient as CFL’s, clocking in at upwards of 120 lumens/watt. Compare to 70 lumens/watt for a CFL. Their spectrum is pleasant, they can theoretically be used on an ordinary household dimmer.
Of course, they’re expensive. The smallest of ‘em, at 20,000 lumens is comparable to a 2,000 watt (!!!) incandescent.
Produced in quantity, the price would go down I’d think. They actually *do* last 8000-12000 hours rather than my CFL’s which seem to burn out after 500 hours on average.
So… why aren’t they a contender?
3 reasons:
1. They are impractical to make small enough for home lighting applications.
2. They remain more expensive due to materials and parts count than CFL.
3. High Pressure=kerblammo! if they break. (Not suited to home use.)
