Do be sure to post here if you start seeing them on Amazon or in stores.

If you want very bright light, though, LED is still not quite there. It might be more subjective than an absolute difference, but I don't think a "75W equivalent" LED looks as bright as an incandescent bulb to the eye. Then again, it only uses 13W of power.


Vision is always subjective. My experience, like yours, has been that the lightbulb manufacturers are not quite comparing apples to apples when they claim their equivalence values.

http://gigaom.com/2013/03/05/cree-launches-an-led-bulb-for-under-10/
--------------------------
http://www.startribune.com/business/201357281.html?refer=y

In March Home Depot started a promotion with Cree and local utilities in which a 40-watt equivalent LED bulb is $9.97, and 60-watt bulbs are $12.97 and $13.97.

ďAs long as the new bulb gives off light like a traditional one, Iím fine with it,Ē

The new bulbs from Cree look and light more like an incandescent than LEDs of old. And unlike nearly every other LED bulb, they can be placed in enclosed fixtures.

After only 10 days, Home Depotís online supplies were sold out twice, local stores have had to reorder and the retailer asked Cree to increase its production, said Mark Voykovic, Home Depotís national light bulb merchant.
---------------
A CFL puts out 65-69 lumens per watt,a 27 watt puts out 1863 lumens,close to a 100 watt incandescent at 1550 lumens.
------------------
http://www.theverge.com/2013/3/5/4068174/cree-10-dollar-led-light-bulb-incandescent

LED at Home Depot....

$12.97 for a "warm white" 60-watt equivalent, providing 800 lumens of light for 9.5W of electricity, at a warm color temperature of 2,700K
$13.97 for a "day light" 60-watt equivalent, with 800 lumens of light at a cost of 9W of electricity, at a cooler color temperature of 5,000K
$9.97 for a "warm white" 40-watt equivalent, with 450 lumens of light for 6W of electricity, again at a warmer 2,700K.

For comparison, a typical 60-watt incandescent provides about 860 lumens, and you can get 900 lumens out of a 14-watt fluorescent, so they stack up pretty well there.
--------------------
So by my muddy math a 60 watt incandescent uses 60 watt
A 60 watt equivalent CFL uses 14 watts
A 60 watt LED equivalent uses 9 watts or so.

Thanks,subject dear to my heart,would love to hear your experiences.


Big +1 to Arney and Izzy's endorsement of the latest LED bulbs from Philips. They are EXCELLENT. The LED bulb folks have finally got their act together.

I bought a two-pack of Philips LED bulbs from Home Depot for $30. After using them in my office for a week, I went and bought a second pack. The colour is perfect, and they don't have that horrible harsh glare that bugs me with the older LED bulbs.

10.5W, 800 lumens, 3000K. Philips model number for the 2-pack is 9290002204. Each bulb has that model number and UL listing "3PM5" stenciled on it.

I have a few rather spendy LED bulbs from Philips and the EcoSmart which I think is a HD trademark. They work okay but the prices need to come down in price before I'll jump in.

OTOH, at the low end of power out I found a Sylvania Candelabra LED bulb that I recently started using in night lights. 0.6 Watts and enough light to make it safe to walk. Not cheap for a low watt candelabra, but in small numbers they won't break the bank and should last longer than the typical incandescent. FWIW.

Nice find, Spuds. I should've mentioned that HD carries them but I've never seen them at my local HD stores yet. But that's where I buy my Philips LED bulbs.

On-off cycling is not an issue like it is for CFL lights.

Note that the packaging on my Philips bulbs did say that they are not suitable for photocell or timer use.

I don't think a timer should pose any problem, and I did use the 75W one on a lamp with a timer for a few days before moving it into the bathroom ceiling fixture. Perhaps that flickering phase on some photocell adapters just as it is getting dark may not agree with the electronics in an LED bulb.

For the latest generation of true incandescent lightbulb replacements, the 60W equivalent seems to be the sweet spot for most LED bulb manufacturers, and that's not bright enough for many applications. But my new Philips 75W is great, so we should start seeing more 75W versions in the near future.

Got the bulbs,Cree 800 lumens,Phillips 940 lumens.

Home Depot has a great selection with the Cree's on an end cap of aisle.

I think I like the Phillips better,it does indeed seem brighter,I understand the praise for the 75 watt equivalent.

I like the Cree too,and its conventional lightbulb form is nice.

Price IMO has reached a viable level.

Light output seems like an incandescent to me.IMO the LED bulb has arrived with these.

Neither is suitable for unshaded fixtures,you will be seeing rings for quite a while if you look into them directly .

Mrs impressed,says "Im Impressed"! From a woman not excited by lightbulbs thats high praise.

Bottom line,Im buying more.Cant wait for the 75 and 100 watt output at the 12 dollar level.

EDIT-Saw a youtube with Cree claiming over 150 lumens per watt on a bulb July of 2011
