    This is pretty remarkable. It's brighter and yet cheaper to make than traditional fluorescents. Could be a game changer if they have good longevity.

    “If these lights were all replaced with 200 lumen per watt LEDs, the U.S. would use around 100 terawatt less energy – saving more than $12 billion and preventing around 60 million metric tons of carbon dioxide from being released into the atmosphere.”

    I read that yesterday, as well. This is a tech that I am keeping my eye on. Sounds like a win/win.

    Thanks for sharing Begreen. Wonder how much thet will cost.
    I have all LEDs in my house. But they are expensive.
    Nobody talks about the fact insects are not attracted to them. I would buy them for
    that alone.

    I have a motion light w/LED bulbs. Works great.
    Also have a bulb in my porch light. No bugs.

    I'd like to see how recycling of this product will go. I run a neon glassblowing shop and have been hit hard by the false claims made by led makers. For example, they claim neon tubing and fluorescent lamps are hazardous waste and can't be recycled because some neon tubes and all fluorescent lamps contain a tiny droplet of mercury, the product is 100% recyclable. I store all my broken or scrap mercury units in a sealed container and they end up at a facility where the glass, mercury, phosphors and metal components are separated and eventually reclaimed. Now I should point out that neon tubes can last 20+ years if installed/processed correctly and the droplet of mercury is less than a pinhead in size, unlike when I first started in the industry and the old timers thought you needed a ball the size of a marble.

    When I service an LED sign the led components can't be separated into recyclable materials and they end up in the landfill. How is this helping the planet?

    LEDs have their niche markets, just wish the manufacturers would stop marketing them as the cure for all the environmental issues.

    How about those LED billboards. We have a fair number around here. Ddistracting. Not sure if it uses more energy than a lit up regular billboard.

    Eeekkk...been looking online for 24W led (120w equiv). The ecosmart reviews say "stay away". And another from lighting science is $48.:eek:....for a light bulb.

    I like that one. I don't think 90W (equiv) is gonna do it, though. I would like to replace the 300w that is currently in there. Going from 300 to 90w is gonna hurt the needed performance. The 120 I was looking at is probably about as low as I can realistically go.

    I'm amazed at how hot the holder can get.

    The comparisons are to t12 bulbs, not t8 or t5

    I have noticed fewer bugs (and spider webs to catch them), but still some. Depends on the species.

    I was amazed too when I got my first CFL, and the my first LED, long ago forgetting how hot incandescent bulbs get. Converting electricity to light still results in much of the electrical energy being dissipated in heat. LED's just have a lot more light and less heat per watt than other types of lighting.

    I bought an LED for the front porch last year and I ended up returning it. I had got the highest power one that would fit in my lamp and it was much too dim. It make the 40w bulb I had in there seem like the sun.

    I take it that they have worked out those issues??

    I put all CFLs when bought this house in 2008, only ones I have replaced where on the back of the garage, they don't do so well with cold.

    For the last several years there were a lot of crappy ones being sold in hardware stores. Almost no light. Several real options now. You need to look for lumens, The crappy bulbs are disappearing, and never have lumens listed. I like all the Phillips edison replacements.

    I just got our first LED bulbs and put a couple in our kitchen pantry area. One flood and one spot, both by FEIT from HomeDepot. The light output is quite impressive, much better than I expected. Agreeing with woodgeek, don't go by wattage equivalents, look at the lumens output.

    The spotlight is a Defiant 40 watt, equivalant to two 75 watt. The bulbs are Phillips I think 800 lumens.

    I recently bought a candelabra LED light bulb but it dont fit any of my candelabra sockets. IT seems most of the sockets are slightly larger than the led bulb, not sure whats going on?
