Quote HistoryQuoted:
Actually LEDs can be dimmed by current as well. I built a supplementary led fixture using Cree LEDs over my reef tank and have 1 ohm resistors that I use to measure current as I vary it at the potentiometer on the driver. Running the chips at higher currents produces a lot of heat though so I used higher wattage LEDs running below their max current 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. Yep, LEDs don't care how much current is going through them, only that there is enough voltage to bias them properly. At least that's what my electronics tech background tells me, I could be wrong considering i haven't knuckled down and read the technical papers on all the new LED bulb tech 
ETA: Caveat to that concerns the operating band for voltage/amperage -- Too little, no sparkly, too much, lots of sparkly which ends with magic blue smoke

I see LED light bulbs as an easy way to reduce our demand for foreign oil. Imagine if every street light in America was switched over to LEDs. Less wasted energy used per night for lighting roads and parking lots. You also have a Better CRI index so you'll see things clearer. My policy is we need to drill for more domestic oil/gas, but also reduce energy consumption on the user end. Changing light bulbs is something that's easy to implement. They're switching. Fly often, you'll see more and more areas, especially new developments, as cold white at night, not orange. As more mercury vapor is replaced with LED, US cities will go from orange sparkles to white sparkles at night. I dunno, seems like all of the LED fixtures around my city have WAY less light scatter. I realize the higher temp is closer to what astronomers are trying to observe, but it appears that significantly less waste light is heading up. |

Then why do all the LED bulbs have massive fucking heat sinks on them? If you spent a little time searching - you could find the answer yourself. LED's convert far less electricity into thermal heat, than incandescent. However, it is imperative to keep the concentrated heat they do generate out of the electronics, therefore LED's often will have a sizeable heatsink, to keep the operating temps of the diodes at an acceptable level. They are susceptible to overheating as the LED generates all its heat in a very small and concentrated area. |

I have about 30 Cree bulbs in my house (40, 60, and 75 watt equivalents). I replaced many of the 100w equivalent CFLs with the 75w Cree LEDs. I wish I knew they were coming out with a 100w version or I would have waited
 .
The 75w bulbs get pretty hot so I worry how long the circuit boards will last. The 100w versions I'm sure will only be hotter. |

CFL's are garbage, I have never had one last more than a couple of weeks, and that's with costing significantly more than incandescents, LED's however rock, I have one in an outdoor light, and despite being left on 24/7, all year long it has not burned out yet, and this is year 3, or 4. |

I went with the recessed lighting fixtures from HomeDepot in my kitchen. They look better (even when turned off)than the old incandescent bulbs. The old bulbs were never straight in the sockets and had the big gap behind them.

I adore the CREE LED bulbs at Home Depot. Every lamp and fixture in the house has been replaced with a 40w or 60w CREE bulb except for some track lighting, including the back porch light that I can leave on 24/7. I hate the look, light and subliminal flicker of CFL bulbs. I like bright, clean low energy LED light. Even if they didn't save me tons of money or last 10+ years, I'd still switch just to get the hell away from the nasty, flickering CFL light.
I may get a few 100w equivalents for the high ceilings if the track lighting will run it. Gonna get out the ladder and check. |

Then why do all the LED bulbs have massive fucking heat sinks on them? LEDs do produce heat but not like an incandescent bulb. An LED is a PN junction which means they will not limit current on their own and if the junction gets too hot they will fail. Small LEDs will dissipate the heat on their own in most circumstances. Lighting sized LEDs need to be cooled or else the junction temp will sky rocket in a few seconds. Quoted:

Quote HistoryQuoted:
Great job Cree. However, there is a dark side to this. This only further establishes the liberial belief that if they mandate and over-regulate, that new technology will some how miraculously be developed. Hence the reason people like Obama would say "cree you didn't build that" If it were not for our government decisions you would not have bothered .etc. http://en.wikipedia.org/wiki/Energy_Independence_and_Security_Act_of_2007 in short (President Bush, a Republican, signed it into law on December 19, 2007, in response to his "Twenty in Ten" challenge to reduce gasoline consumption by 20% in 10 years.) It doesn't matter who's idea it was to move away from old to better tech. I would never have looked at "other than incandescent" if incans were still available and I doubt any Cree light bulb threads would even exist. Don't be so narrow minded that you can't accept a better solution because of who you think came up with it. Side with those who demonstrate your shared belief, not what colors they sport. And yes, you are correct in that, who would invest in the new tech if mandates hadn't changed the game. |

Yep. I'm 40 miles from the Hoover Fucking Dam and my bills are routinely $300. Way more in the summer. For a 1,300 SqFt house. Horseshit. I'll be traipsing off to Home Depot to retro fit ASAP Quote HistoryQuoted:

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. Not everyone lives the same or pays the same per KWh for electricity. My electric bill averages $400 a month.

I am locked into 9.7c for 18 months with ENH, which is cheaper than PSNH's demand spikes. |

IIRC, Cree makes the chips in the US, sends them to China for packaging, then gets them back to actually assemble the bulbs with. Seriously. Quote HistoryQuoted:

Have Cree's always been made in the US? I know they were always one of the top LEDs on the market, just always thought they were made in China? If they are all truly made in US I have no problem with paying more for them. I think they "assembled" in the USA from chinese parts... Hmm. Are these new line of bulbs supposed to have all parts manufactured in the US or just assembled with all Chinese parts? 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. Seriously. Stuff like this always gets out of from me.
So the diodes ARE made in the US then? That's pretty neat that we're making them here in the states. They really need to expand, but obviously a much more costly upgrade to do here in the states. |

Packaging could mean shipping box or it could mean finalization of the part. There's a good chance Cree builds the actual junctions here to keep their manufacturing magic safe from unsavory people and then sends them to China to have the lens or protective coating applied. The secret sauce where Cree's hard work lies in the PN junction. Finalizing the part, QA, binning and packaging are things China is super efficient at doing cheaply. |

2800K, IIRC. I prefer 3200-3500, personally. I hate the 5000K ones. Quote HistoryQuoted:

I wonder what k it puts out? 2700k, 5000k? What is the best for inside a house? I prefer 3200-3500, personally. I hate the 5000K ones. My brain actually white balances automatically so that what I look at looks white under any but the harshest after sunset light.
