Doh! I just replaced my entire house with the CREE 75W 2700K bulbs... 100 lumen difference shouldn't make a difference.

Another real-world example - I just replaced 4 65w hi-hats in my home office that run 16 hours a day. I bought these bulbs - http://www.amazon.com/gp/product/B00B4CPKT4/ that make the room brighter than the old bulbs ever did. Total investment $83.88. Old usage - 65w x 4 x 16 = 4.16 KWh per day @ $0.16 per KWh = $0.64/day = $242.94 per year New usage - 10.5w x 4 x 16 = 0.672 KWh per day @ $0.16 per KWh = $0.11/day = $39.24 per year Savings in electricity - $203.70 per year (plus about $15 in replacement bulbs) Your room will also be noticeably cooler than it used to be. I replaced the under cabinet xenon lights in my kitchen with LEDs and knocked the normal temp in the room down by 10 degrees. Good point, that will save me even more $$$ in the summer as the office is in the attic and really heats up. Of course that's only July and August for you. |

100 watt equivalent or 100 watt actual. With LED there is a HUGE difference. a 100 watt actual LED is enough to run a grow operation off of. Not enough heat, nor the correct UV wavelength to grow anything off of it.

I can vary the brightness on my fixtures from just enough light to see the bottom of the tank to holy shit that's gonna fry something You're only scratching the surface of what you can do with even lowly 8bit PWM. You're also losing the effiency that you get from running the LEDs in their optimum range. Dimming with PWM scales the efficiency with the duty cycle. Quoted:
Not sure on the brand, but the light in the nursery is some new-fangled LED I bought at Home Depot. It just isn't the warm light one gets from real bulbs. I'll give it points for longevity, sure, but outside of nightlight duties, I am unimpressed so far. My flashlights? Sure. Weaponlights? Of course. Even certain low-use duties around the house (in the shed, for example), why not? But my living room? Not yet. You got crappy LEDs. Buy a bulb with 90+ cri, in the 2700 - 4500 heat range and get back to us. Quoted:

I have bought about a dozen of the 60 watt Cree bulbs as well as a few 40 and 75 watt bulbs,
I like the 2700 K spectrum light (soft white). They are good bulbs and disappear from the HD shelves as fast as they put them out. I am pleased to support a US manufacturer. I would try the 100 watt if I needed one. I replaced over 50 bulbs with LEDs and my bill went down about $60. These will pay for themselves in about 2 years. However, I keep every receipt and package label and if any of them go out before the 10 year warranty I will demand refund or replacement. |

What kills CFLs is short cycling. They do not work for closet or bath room lighting where burn time is minutes rather than hours. On at dusk, off at dawn, they will exceed their estimated run time. They are very heat sensitive, and some can not be installed base up, or thy will burn out in short order.
Interesting that Cree is instant on. Phillips builds soft start circuitry into their LEDs because they claim the instant on shortens board (not actual LED) life. Only actual field use will confirm if the LED lives up to the longevity claims. A post above states he saved $60/month on his power bill, WTF? With HVAC, water heating, cooking, and lighting, I rarely have a total elect bill of $60 in one month. For the above mentioned lighting, that house must be used as a landmark at night for the Space Station. |

Quoted: $20 for a light bulb? View Quote Still WAY too expensive, when I can buy honest 800 lumen 13 watt compact fluorescent bulbs that replace a 60 watt incandescent bulb, that I pay LESS than $1 for, including sales tax. I bought a pack of 8 CFL's for less than $7. That was 3 years ago. I've only used half of them, to replace burned out fluorescent bulbs. No LED's for me until they come down at LEAST 60% in cost. Twenty years ago, compact fluorescent bulbs cost $10 - $15. They were new. |

I have an office with no lighting. I use a torchiere lamp, to throw light up, and it needs a 100w bulb to accomplish anything. They fail/go out ALL THE TIME. I just had to replace it again yesterday. I bet I go through at least 4-5 bulbs a year (this light sees a lot of use as it is my office), not to mention the cost of electricity. $20? No problem, will be picking on up next time I am in the area. |

$20 for a light bulb? Considering it lasts well over 11 years, and doesn't waste energy, by turning it to heat, its a good deal. While I disagree with a ban, and it should be left up to the people to decide, in the long run, its much cheaper than incandescent. Just because it puts out heat, doesn't mean the energy is wasted. I'd guess about 2/3 of the time that the average person used incandescent lights, the heat was a beneficial side effect. In some situations an incandescent light is an economical method of providing heat to a small area. |

As far as I knew all LEDs were Chinese made, including Cree just because of they way they are produced and we aren't set up here to make the diodes, let a lone for a cost effective price like Chinese made LEDs. |

For the people that can't get past the $20 price tag let me throw something at you.
Socal Edison has pretty expensive tiered pricing. During the summer when you are running a pool pump and an AC it's possible to get into tier 5 pricing which is mucho dinero. LED lighting can make enough difference to keep you in tier 3 or tier 4. The savings on this is way more than what the manufacturers are claiming. I could recoup the cost of some of my lights in one summer. |
