Liquid-cooled LED light is first 'eco' light that's as bright as a normal 100w bulb

A new generation of liquid-cooled LED light bulbs are set to go on sale, which will result in energy savings for consumers.
The revolutionary design, which has been developed by makers Switch - a Californian-based firm, offers a longer life and a better performance than a regular bulb.
However, unlike the traditional design, it will use a fraction of the watts to emit a brightness that matches up to its 100W counterpart.

Looks like you would never recoup the cost of the bulb compared to a CFL and probably lower quality of light VS a CFL

Any idea what frequency of light they emit? 2700k or 4700k? I wonder

Probably available in a choice, as most high-end LED bulbs are.

Certainly, the high-end Philips bulbs are available in 2700K (incandescent equivalent), 3000K (halogen equivalent) and 4000K (neutral daylight simulation).

It depends. Probably not for home use.

However, for commercial units, like offices and shops - where the lights are on for prolonged periods, and you have to pay a handyman to change the bulbs on a regular basis, there is a definite cost saving in not having to replace bulbs as often.

Light quality is likely to be better than CFL. Reduced flicker due to electronic drivers, and higher color rendering (CRI of better than 90 is not uncommon on high end 2700K white LEDs - but it basically unachievable with CFLs).

So, irrelevantly expensive.

Home Depot now has 40W LED by eco smart for $8. They are on display and turned on in some cases. Not terribly bright, but about the cheapest LED bulb I've seen. Course, CFLs keep getting cheaper and I have to admit their slow turn on time I'm getting used to as much as I think I should hate it.

Would take about 4 years at 3 hours usage per day and power cost of 10 cents/kWh

READ the article again, it is 80% more efficient than a INCANDESCENT Bulb, not a CFL. It is essentially no more efficient than a CFL.

You could use this bulb for 30 years nonstop and you would still not recover your cost.

This bulb will struggle to take off at a $37 price point. If their 60W equivalent cannot compete with the Philips model's price of ~$30 per bulb, they are really going to be in trouble.

Oh for reference, the first incandescent bulbs cost about $11 (adjusted for inflation) when they were introduced. I realize this is a vastly different set of circumstances however I thought it was interesting to note.
 
I have a single light in my house that requires a fINg cherry picker to access.

So for people with 30ft ceilings and no access to the light up there: This might be a good choice.
