Thanks. That bulb is a bit pricey ($45). It sounds like most LED bulbs are a little cooler than traditional incandescent. If I go this route should probably obtain an inexepensive one to see if it is a big deal; I thinik the lamp I mentioned above is a bit cooler than these LED.

An incandescent bulb is 2,700 - 3,300 kelvins (Source). If these are truly 3,000 kelvins, then it should have the same warmth of light.

As far as wattage per lumens goes, it seems to vary. Here's a 13W LED that claims to be a 100W equivalent. However, it produces 1075 lumens instead of the 1,750 lumens that a 100W incandescent produces. That "100W equivalent" is much closer to the 1210-lumen output of a 75W incandescent. I don't know much about LED bulbs, so maybe there's something with them that allows them to seem to produce more light with fewer lumens.

What brand and color temperature did you get?

I didnt buy my bulbs off this site....I have 6k, 4k, 3200K, MR2 type, bipin leds throughout my house. All my leds are warm white in my house, bright white outside. Ive spent at least $1k in bulbs keeping in mind that I have 50 potlights in my hosue that were using the halogen bulbs, now they are on par 38 11W led equiv lights( close to a 60W bulb) Ive never replaced 1 led bulb to date. Its been 1 1/2 years since Ive gone all LED. I also have par 38 potlights outside my house that are 11W LED.

The light intensity all depends on the room that you want lit. I have dimmable 6k warm whites in my kitchen ( 11W led), 3200 WW dimmable in the living area.

eventually the whole fixture will just have the LEDs integrated into them, and you'll change the LEDs with the fixtures. kind of like a ceiling fan. your ceiling fan doesn't wear out every 6 months and get changed, now does it?


maybe.

I've bought a "few" 120vac LED lights, but in general, NOT READY, CFL for a couple more years at least, then I think we will start to see LED coming in more not as replacement for bulb fixtures, but whole new designs made for LED, wiring, controllers, and fixtures.

The catch is going to be for a long time, nothing sells like the sparkle possible with incandescent lights, and new houses need to get sold.

This is how I feel too. I love me some LED flashlights and have seemingly dozens, but all the LED bulbs I've purchased except the ones in fixtures were all yanked and now sit collecting dust with the other spare bulbs.

The ones in fixtures I actually like. Got 'em from Ikea. Some were desk lamps with weighted bases and flexible goosenecks. Others were stick/screw on meant for underneath shelving. Love 'em! Also have some LED light strips that are nice, but don't quite have a good use for them yet.

I just got these bulbs in and swapped it for a CFL, can't really tell the difference

Will gladly use these around the house. We have problems with CFLs going out for some reason.

LEDs are nice, but they aren't bright enough. LEDs can't replace 150W or 300W Bulbs.

Why did you spend so much money on those bulbs? Seems to me like they will take a horribly long time to reach the break even point.

they dont make affordable leds that can beat 150w or 300w bulbs. they do make them though. just wait a few more years to buy them in quantity

CFLs are bad for the environment.

How come you do not claim the same with the regular fluorescent tubes? We used far more regular fluorescent tubes in office buildings than we do CFL's! What about the electrical energy used by regular incandescent bulbs, isn't that bad for the environment also considering it requires electrical companies to burn more coal or petrol? The only reason I believe that makes CFL bad for the environment is because it's so effective and efficient and the environmental nazi's are not getting a cut off it!
