Great to see a US company be able to compete on price while providing a superior product.
Going all LED in our new house, currently have LEDs in high use areas in this house and am very happy with them. |

Here's an example of savings:
Lets say you have a room with 4 100w lights that are on an average of 4 hours a day and replace those with 4 18w LEDs. Before replacement - 400w x 4hrs = 1.6KWh per day, at $0.16 per KWh (what I pay for electricity) that equals $0.26 a day or $93.44 a year. After replacement - 18w x 4hrs = 0.288KWh per day, at $0.16 per KWh (what I pay for electricity) that equals $0.05 a day or $16.82 a year. That is a saving in electricity of $76.62 per year for 4 bulbs, in other words the bulbs pay for themselves in just over a year. But they have a 20 year lifespan, during which time you would probably buy 20 replacement bulbs at $1 each, so $20 (bulbs) + 20 x $76.62 = savings of $15.52.40 over 20 years for just one room and 4 bulbs. |

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) |

They make great bulbs. I read somewhere that their magic designs almost exclusively come through one guy and his team. He is responsible for over 80% of their patents in this market. A regular J.M. Browning of lightbulbs.
edit: Folks, this is not a 100 watt bulb, but rather puts similar output to a 100 watt incandescent. Same thing applies for their 40w and 60w versions. I think the 60W is something like 13watt for its current.

no, it won't, based on my experience with other "electronic" based lightbulbs. Mainly CFL's and a couple LEDs.

Sure, the LED might be good, and the poisonous mercury vapor mix in the little tube might be good for a millenia, but if the %@$@$@# bulb won't turn on, what good is it? these new bulbs are a red herring.

I was a HUGE proponent of CFL/LED lighting early one, but I got stung. I spent a crapload on lights that just die right away. I'll wait til these bulbs can prove the actually last as long as they say they do. Not based on estimates, but when these bulbs literally last ten years. |

Ok. Now factor in the time-value of money and let us know how many bulbs that extra money save up front frrom using incandescent bulbs could have bought at future dates invested at the risk-free rate? What about in the stock market at average rate of return?

Quote HistoryQuoted:
I hate CFL, hence the reason I hated the anti-incandescent legislation. Thank you Cree, for kicking ass and offer something I would have bought regardless. Now, you just need to figure out how to do a 3-way bulb. LEDs can be dimmed with a process called pulse width modulation (pwm). It's basically turning the diode on an off quickly which through persistence of vision makes it appear to be dim. Regular dimmer switches are big variable resistors that limit current to the bulb. An incandescent light glows due to the amount of current flowing through the filament. Dimmed LEDs still require full current to work so a standard dimmer has little to no usable effect on them. I suspect we will see new dimmer switches for LEDs that communicate to a pwm controller in the bulb. Three way LED bulbs don't require any special lamp/fixture hardware beyond what is required by a 3 way incandescent bulb. A normal bulb has two contacts. Current is either allowed to flow through or not. Three way bulbs have three contacts and two filaments of differing wattage. You can power the low watt filament, the high watt filament or both to get your three brightnesses. A three way LED bulb would work exactly the same way. It would have two constant current drivers and two discrete strings of LEDs. They even make units with many individual LEDs on one die. |
