I’d like to try out a LED but my CFLs just won’t wear out. And I picked up a half dozen spares for $0.50 each a couple of years back. I’m many years from needing to buy a new bulb.

My first CFL is now functionally done. And I’ve got a second which has started taking longer to reach full brightness. That’s over 15 years. I might actually skip the LED era and replace with whatever comes after them.

I (with help) actually built the lighting for my room with 40 1w leds: ( http://www.ebay.com/itm/50-Pcs-1W-High-Power-Cool-White-Led-Lamp-Beads-90-100-Lm-5000K-/330722723619?pt=LH_DefaultDomain_0&hash=item4d009c4723 ) underdriven at 150 mA-s instead of 300 so that it doesn’t require cooling and is more efficient. I fixated them on a cable duct the whole length of the room so I use the light more efficiently (because the light is more diffuse and there’s very little shadowing.)
Anyway all in all I use less than 20W-s for the lighting for the whole room on full power, which I rarely use because it’s unnecessary.

Point-source lighting is a relic that will persist only for a time, while we try to pull value from expensive bulb fixtures, as decor. In tricking LEDs to deliver omni-directional light, more than half of drawn energy is wasted, where task lighting is wanted. We can not, and will not, tolerate such waste.

LEDs allowed to deliver directional light upon a task give more than times-two task illumination for produced lumens. LED directional flood and track lights have this “surprising” excess vs. stated lumens, and replace incandescent, halogen and CFL bulbs as best-buy. A cheaper LED omnidrectional bulb is not yet a better buy than a CFL.

I comment on this with a good bit of dismay. Best residential lighting for the past two years has been Glimpse, from Lighting Science. All produced light beams from these simple Plate LEDs. They are the best alternative to a downlight can, and permit elimination of cans often criminally-hacked-in by the dozens in a fancy new home or deluxe remodel, left to bleed heat where placed in attic floors. Who noticed the Glimpse lights? Who raved about them? Who has worked to deliver better models due after two years of experimental and slim production?

Let us promote best possible LED lighting, at lowest possible cost.

The thing that these do give up on a bit is Color Rendering Index. They only have a value of 80 (Which is the minimum to be considered Energy Star applicable) where the L-Prize bulb has a rating of 93. Just for reference, the cheap CFLs are in the 70s normally but can go as low as 50 or 60 CRI. The CFLs that are Energy Star rated are all above 80 CRI and can go into the mid 90s, but these higher ones are typically expensive. Basically at a value of 80 most people wouldn’t be able to tell a difference, but if you are light sensitive the L-Prize bulb might be worth the extra.

Definitely going to try one of these next time a bulb burns out. (Which might actually be a while – these CFLs just never seem to die. Haven’t had to replace one yet)

Also, for those wondering – all 3 versions are dimmable.
