Re: Liquid Cooled LED Bulbs said by Jack_in_VA:IMO cost is something that prevents LED's from being an alternative except for those with large disposable incomes. The average person does not have that kind of money to invest in them. It's more expensive but it's not like we're talking about mutual fund GMGWX which is a $10 million initial investment and most people can't get there if they wanted. LED bulbs are something anyone can buy if they want. The average person can afford them if they want unless you think the average person can't afford to eat out for $10-12 either. I think what prevents people from buying them is the ROI between CFL's and LED's. Most people just don't think long term so a 5 year break even isn't appealing. People want to save $7.50 today instead of $20.00 over the next 15 years. We want instant gratification!!!

kudos:1 | I disagree. The family struggling to provide housing, food, clothing, healthcare is not going to have that kind of money available. We in our affluence have lost sight of the conditions most people have in their daily lives.
I can well afford them but I don't intend to buy anything that over-hyped and over-priced.
Right now IMO they are a niche "feel good" product. Nothing more. The price has got to come down dramatically for LED to be anything else.

So the market niche defines the specific product features aimed at satisfying specific market needs, as well as the price range, production quality and the demographics that is intended to impact. It is also a small market segment.
A market segment of people with ample income as to be able to discount and ignore the high cost of a product. |

By that token CFL's are a niche market since incandescent bulbs are like $.50 compared to the $2.50 CFL compared to the $10-12 LED. Notice how the price jumps up by about the exact same factor.
Average household income in 2011 was $51,413 FYI. Yes some people can't afford it and some can afford it without thinking about it. All we can do is talk about averages or the majority of people.

Re: Liquid Cooled LED Bulbs The problem with LED is people. Consumer grade self ballasted CFL was a horrible stop-gap replacement for incandescent lamps. It didn't start out that way. When they first appeared on the market, many were made in the US of quality materials. That quickly changed when they moved manufacturing to China. Quality went out the window.
I began writing the install date on consumer grade, self ballasted, CFL lamps after noticing a high failure rate. This confirmed my suspicion that the lamps usually failed within 1 year. Not only did they fail, but they often failed spectacularly in what I call a "blaze of glory" (shooting flames emitted from the ballast at the base of the tube).
This was several different brands purchased at several different stores.
Consumer grade CFL's can't give a pleasing color, regardless of what color temperature you buy. The "fade in" is extremely annoying. The "dimmable" lamps are barely dimmable. Let's not forget mercury and disposal issues.
LED's have the potential to be different. I say potential, because we are tracking down the same path as CFL - all made in China junk.
With LED, we lose the mercury toxicity. They dim much better than CFL. They are "instant on". They are able to closely mimic the color output of incandescent lamps.
Back to people being the problem: You have to think of an LED lamp as an appliance, and not just a disposable item. That being said, with all manufacturing moving to China, I can see quality issues being a huge problem for LED. Paying $20 for a lamp, and it only lasting a year or two will really burn people up. I save every LED lamp warranty for myself and my customers.
Example - I just did an install of 21 LED fixtures for a commercial customer last week. They refused to go CFL because of the poor light color. Their lighting load went from 1600W to 300W - A savings of about $850 per year. The lamps will pay off in about 8 months. The entire job will pay off in about 2.5 years.
For those with an open mind, I did the math on this a while back in another thread: »Would you pay $50 for a light bulb?

kudos:1 | I have an open mind and can well afford it but there's no way I'll ever spend $50 on a light bulb.
I remember doing homework by kerosene lantern so the color of some CFL's doesn't bother me at all. Light is light except the god awful blueish that I see on the LED Christmas lights. Looking at those takes the joy out of looking at the decorations. |

The flicker of Christmas LED lights is my big gripe. Since I don't see any space for rectifiers in the cord I have a feeling they are half-phase. And even if they were full phase there are certainly no capacitors to smooth it out. |

Power: CFL $6.9496 - LED $6.205 = $0.7446 ($17/Kwh)
Cost: LED $12.97 - CFL $7.4625 = $5.5075
$5.5075 / $0.7446 = ~7 years 5 months to break even / If you take a 20% Kwh increase into account it's ~6 years
Power: CFL $4.25152 - LED $3.796 = $0.45552 ($10.4/Kwh)
Cost: LED $12.97 - CFL $7.4625 = $5.5075
$5.5075 / $0.45552 = ~12 years to break even / If you take a 20% Kwh increase into account it's ~9 years 7 months
As you can see how much you use a light and your power price play a large role in figuring out what's cheapest over a given period of time. If you factor in a 4.1% annual Kwh increase that reduced the ROI by about 20-25%. Anyone can see incandescent are just a money pit while CFL and LED fight for most cost effective spot based on usage/Kwh rate. If the light is hard to access like a 10+ foot ceiling you need to add more cost onto the CFL to account for the man hours to pay someone to replace them 2.5 times more often. Lots of other factors play into it but this is just a basic rundown to get people started.

kudos:1 | I'm paying $115/mo budget plan right now. Paying almost
1/2 of my current electric bill for a light bulb doesn't make any sense at all.
If saving money was really an issue everyone would be buying the "Smart Car" instead of their preferred vehicles. or I could buy 2 Chevrolet Cruz (one for me and one for the wife) for what a Chevrolet Volt costs. |

WTH are you talking about 1/2 your bill for a bulb? You are fixated on $50 but that's a mythical price just like your stance. Just leave it alone or say it's not for you but don't make up some mythical excuse. Your dead set against it and that's all you need to say. The truth will set you free!
I checked the Gloucester, VA Home Depot for you on that.

Thank you Spark. The lengths that some will go to justify the unjustifiable in some cases is amazing.
Most of my lighting 90 percent is CFL that I've had very good luck with. I bought a bunch of them when Dominion Power gave rebates at Home Depot several years ago. Only had 2 failures and they were in table lamps base down. I have some in enclosed ceiling fixtures that are doing fine. |

The reply was talking about a 60 watt that's $24.97 @ Gloucester, VA Home Depot. It's not a good option for him but a FAR FAR FAR cry from wolf that he's calling. He just needs to play in reality and people won't have to call him out. |

Re: Liquid Cooled LED Bulbs I find it slightly amusing how debates about lighting tech or hot water temperature around here become as heated as any political or religious debate could be expected to be.  |
