LED Light Bulbs?
Anyone invest in any yet? Do they provide more light than a compact fluorescent?
Reason I ask is I have two large lamps that have CF bulbs, (equivalent to 125W each) and I'd like more light. However, given the CFs are only 35W each, it's a decent amount of light for the power they consume.
Can I get more light with equal power consumption out of LED bulbs?

I've been wondering about bulbs myself lately. There so many different options these days.
I've heard that incandescent bulbs are supposed to be banned in a few years. Any truth to that?

As for using them, I haven't even seen them for sale and haven't ever seen any LEDs that produce "natural" looking light so I'm not in any hurry to switch over to them.

LED > Flourescent.
I hate flourescent lighting and I always will. The company my father works for is supposed to start shipping LED under-cabinet kitchen lighting this month.

This link http://www.ccrane.com/lights/led-light-bulbs/index.aspx makes me think that they won't help you.
The bright, white LED light produced by our LED Light Bulbs works especially well for task lighting and reading light. LEDs not only produce light more efficiently, they also have a tiny mirror that reflects light in one direction.
To get familiar with LED light bulbs, we recommend you experiment with different lighting combinations and see how their reduced light output works for you.

I recently switched to all CF bulbs. My only gripe is the lag time to "warm" up. Once on they are nice. Id like to know as well about the led home lights(wish they were a bit cheaper)
I do have all led night lights and they are nice

can anyone recommend some good CFLs to replace 60-75w bulbs? These are for a closed glass lighting fixture....they need to be the same size as reg. bulbs...i dont want to order something online and have it be the wrong thing.

Not a fricking clue about home LED's. Only LEDs I've seen for residential use were Christmas lights and they pretty much sucked butt unless you were within 20 feet then they put out enough light to look ok. Only applications I've seen with LED's for high output involved an array of them (like a dozen or more) to produce the effect - not sure how practical that would be in most of our light sockets.
I have four can lights in my family room, used to have four 100W incandescent bulbs - replaced them with equivalent output flourescent bulbs (at 24 watts each) and reduced energy consumption by 75% - with a subjective improvement in the intensity and color of the light. Now I don't really care if lights are on when I come home and nobody is in the room.
Basically, in my house certain lights tend to get left on by my wife - these get replaced with flourescent bulbs - but yeah, it takes them about 60-75 seconds to reach full intensity which is annoying.

They were priced the same as the ones with normal ballasts.

This pisses me off, if you have to turn the light on for just a few seconds and leave the room. I have a couple of CF spotlight blubs in the spot lights in the basement, they take forever to come and don't last worth crap. I've started just putting regular CF blubs in.

I feel the need...
Fans of L.E.D.’s Say This Bulb’s Time Has Come
When the Sentry Equipment Corporation in Oconomowoc, Wis., was considering how to light its new factory last year, the company’s president, Michael Farrell, decided to try something new: light emitting diodes, or L.E.D.’s.
“I knew L.E.D.’s were used in stoplights. I wondered why they can’t be used in buildings,” Mr. Farrell said. “So I went on a mission.”
What Mr. Farrell found was a light source that many of the biggest bulb manufacturers are now convinced will supplant incandescent bulbs and compact fluorescent bulbs.
By lighting all of the building’s exterior and most of its interior with L.E.D.’s, Sentry spent $12,000 more than the $6,000 needed to light the facility with a mixture of incandescent and fluorescent bulbs. But using L.E.D.’s, the company is saving $7,000 a year in energy costs, will not need to change a bulb for 20 years and will recoup its additional investment in less than two years.....

I don't think the avg consumer understands the mercury contamination risk of CFL's. Good thing the Gov't is mandating a phase out of irridescents then.

it's me, Alan Rickman.
To the OP - sorry about my long stupid rant.. check these out:
http://www.superbrightleds.com/MR16_specs.htm
The CFL law is stupid and I refuse to do it; first of all.. CFL light output isn't the same as regular bulbs, and the fact that when a CFL breaks you have to evacuate the room for 15 minutes, get fresh air into it, turn off your HVAC system so you dont spread mercuy vapor around, is total bullshit. You cannot use a vacuum to clean up the broken glass as it may cause harmful vapors to get into the air. It's stupid.
AND YOU CAN'T DIM THEM! SO THEY ARE THE SUCK
Regular bulbs or LEDs are fine with me; CFLs.. heck no.. also none of them are made in the USA and are anti-americanecnomoyish.
From EPA.gov:
Before Clean-up: Air Out the Room
Have people and pets leave the room, and don't let anyone walk through the breakage area on their way out.
Open a window and leave the room for 15 minutes or more.
Shut off the central forced-air heating/air conditioning system, if you have one.
Clean-Up Steps for Hard Surfaces
Carefully scoop up glass pieces and powder using stiff paper or cardboard and place them in a glass jar with metal lid (such as a canning jar) or in a sealed plastic bag.
Use sticky tape, such as duct tape, to pick up any remaining small glass fragments and powder.
Wipe the area clean with damp paper towels or disposable wet wipes. Place towels in the glass jar or plastic bag.
Do not use a vacuum or broom to clean up the broken bulb on hard surfaces.
Clean-up Steps for Carpeting or Rug
Carefully pick up glass fragments and place them in a glass jar with metal lid (such as a canning jar) or in a sealed plastic bag.
Use sticky tape, such as duct tape, to pick up any remaining small glass fragments and powder.
If vacuuming is needed after all visible materials are removed, vacuum the area where the bulb was broken.
Remove the vacuum bag (or empty and wipe the canister), and put the bag or vacuum debris in a sealed plastic bag.
Clean-up Steps for Clothing, Bedding and Other Soft Materials
If clothing or bedding materials come in direct contact with broken glass or mercury-containing powder from inside the bulb that may stick to the fabric, the clothing or bedding should be thrown away. Do not wash such clothing or bedding because mercury fragments in the clothing may contaminate the machine and/or pollute sewage.
You can, however, wash clothing or other materials that have been exposed to the mercury vapor from a broken CFL, such as the clothing you are wearing when you cleaned up the broken CFL, as long as that clothing has not come into direct contact with the materials from the broken bulb.
If shoes come into direct contact with broken glass or mercury-containing powder from the bulb, wipe them off with damp paper towels or disposable wet wipes. Place the towels or wipes in a glass jar or plastic bag for disposal.
Disposal of Clean-up Materials
Immediately place all clean-up materials outdoors in a trash container or protected area for the next normal trash pickup.
Wash your hands after disposing of the jars or plastic bags containing clean-up materials.
Check with your local or state government about disposal requirements in your specific area. Some states do not allow such trash disposal. Instead, they require that broken and unbroken mercury-containing bulbs be taken to a local recycling center.
Future Cleaning of Carpeting or Rug: Air Out the Room During and After Vacuuming
The next several times you vacuum, shut off the central forced-air heating/air conditioning system and open a window before vacuuming.
Keep the central heating/air conditioning system shut off and the window open for at least 15 minutes after vacuuming is completed.

90% of my lights are dimmable. Electrician tells me that while they sell dimmable CFs, there is no UL listed dimmer available for them. He says he won't install them, and my insurance may not cover the fire.
I asked him for some LEDs. He said they are low voltage, and he would have to install transformers in the basement, and the project would cost 5x anything else.
Sticking with the energy hog halogens, except for under-counter, going with low voltage xenons.
The time for pure white LEDs at a reasonable price might be 20 years away. Looks like I can't afford to save money on electricity

RE: The low voltage; any LED bulb replacement would have internal transformers or resistors built in so I don't think rewiring would be required; however it will still be using 120v, and to drop it down to 5v or 3v for the LEDs would require heat sinks for said equipment, which means massive heat dissapation.. probably why they warn excessive heat [ie putting the LED bulb in a sealed box] will shorten the life span.
So I guess the question, is a LED replacement bulb more efficient than a CFL?

You're saying with all that heat loss they're still more efficient?
Don't get me wrong, even with the heat loss I'd rather have LED vs. CFL but i'm curious if people are assuming LED replacement "bulbs" are more efficient because in practice.. they are.. but are they efficient in a 120v household setup?

LED bulbs are going to cost a hell of a lot more than even the CFLs. Mainly because you are not going to be replacing them very often, so the manufacturer has to make the money from the original sale, rather than the replacement sale every couple of years.
