LED Lights anyone?


The LED christmas lights I have don't seem to make any heat at all. Then again, they don't make a lot of light either. So I am surprised that the dealer experienced an "up in smoke" scenario. Perhaps it was more a wiring problem in the light string than the actual LED.
I tried to see how much heat my LED headlight put out yesterday. Left it on for 4 hours straight. It was cold. Not even a hint of warmth.

LED Lights anyone?


LED strings that are properly setup are full wave - this eliminates the flicker & allows the LED to perform at its "best"
The strings in question will work without any problems for most people. But the site I am on is full of people who "animate" their displays & the lights dance to the music. This was the problem, but buyers were assured that these had been tested & worked with the animation. But the MFG changed the design

Cheap LED strings are not setup correctly, have flicker, are not as bright as they can be, may have sockets that corrode, plus other problems

Thanks for that, again very interesting.
I can't say I have noticed any flickering on mine, except for one of the three lights in my headlamp now that you mention it.
Two of the lights are steady. Sometimes the third light flickers, and sometimes it is steady. I guess something might be loose inside.
It's about two years old now and I have never even looked at the battery.
Surprising it has lasted so long, as it gets a lot of use. Shows how little energy these guys really do use.

I bought some LED Mag-Lite flashlights before Christmas this year. They are much brighter than flashlights with regular bulbs and the batteries are suppose to last a lot longer. Why are the LED lights we use in a house dimmer, but for flashlights they're brighter?

It has something to do with both how they are mounted in the lights themselves, and also whether or not they have the proper outlet for the actual light beam.
I know the flashlights really do look bright, but they focus all their light into a very narrow beam.
Many of the household LED's also have a fairly narrow focus, and I think this is because each of the LED's has a tiny reflector behind it forcing the bulk of the light to go in one direction.
Whereas a fluorescent or incandescent light creates light either by heating up an element or exciting a gas. This light will travel indiscriminately in any direction, therefore filling a room with light, and giving the impression that it is brighter.
I have just found out that one of our friends at the other end of the island has soldered together something like 200 units to make a grow light. He is a chef and wants to be able to grow fresh greens all winter here. He has also made himself a cooled growing area inside his house. Winter greens do not like warm soil apparently. I haven't been up to check it out, but he tells me that the light is so bright there is no way you can look at it.

I wonder how big of an area 200 of them covers. I can imagine it would be extremely bright. He'll have some happy plants.

One tiny LED flashlight I bought to keep in the nightstand and to read with came with a warning on the package not to look directly at the light. When I was buying the flashlights, I thought I'd grab a few extra bulbs just to have around. Ha! That didn't happen. If I remember right, one little package of 2 bulbs was $18.00. I'm surprised they don't have them locked in a glass cabinet like they do video games . Since the flashlights were on sale and my son-in-law was able to get another 30% off, the replacement bulbs cost more than what I paid for the flashlight with an LED bulb in it.

I don't know what the 200 cover, but if he is growing winter greens, it must be at least the equivalent area of several seed flats. I will have to wander up there and check it out. It is a fairly long walk up there, so that will have to wait 'til it warms up a bit.

kbsparky:
Please forgive my ignorance, but is Sam's club a regular type store or something online? I have not seen one up here in the wilds of western Canada.
That spot is what I am looking for. Perfect for the kitchen.

Sam's Club is similar to Cosco, a wharehouse type store. Those bulbs are priced well, at $14.86 each plus shipping (you can purchase on-line). When I was reading the consumer comments, they sound like they perform slightly less than described (slight blue light vs warm white, 15-20W comparable vs 40/45) but not sure if those comments were for both lights. Still might be worth trying one before committing to buying a large lot.

Thanks Wrangler. I went online last night and found Sam's OK, but there were no prices for the spots that I could find.
There seems to be a variety of light that you can get, i.e. warm white, cool white etc.
One of the sites I ran across provides the Kelvin temperatures for each type and describes what it is closest to. Guess I will have to find that one again and pay more attention this time!!

Cocobolo, if I remember right, in Canada you have The President's Club which is one of the 'pay to shop' stores like Sam's Club.

I know there is a President's Choice brand, which is sold through a variety of stores, notably Superstore up here.
The only pay to shop place I know of out west is Costco. I haven't checked in there yet, but we do have a Costco over in Nanaimo, so maybe worth checking out.
I think it is just a matter of time before these LED's become widely available and at lower cost.
Still looking, as I am anxious to get some ASAP.
Even using solar power, our energy cost is high in winter. Due to the fact that we need to run the generator every day. We all know what the cost of gasoline is, and this makes our KWH price positively stratospheric!

Try doing a search from the Sam's Club site for 116186 and 116198. I noticed there is a slight price diff for diff stores(14.86 here vs 15.26 in Seattle)

Actually, I have found what appears to be a very similar light, possibly identical, for $16, which includes free shipping to Canada. So that will likely be my choice for now. I will keep looking, just in case. I have 5 cf's up there now, so for me that is just around a 3 amp draw on our solar system. More than I would like just for a few lights. Really looking forward to the LED's.

on the comment about mag-lite flashlights with the LED inside, the led itself is a 3watt led, that is one main reason why the bulb appears to be so much brighter. check out this website if you are truely interested in LED lighting, I found it to be very helpful, and a broad range of products- http://www.ledliquidatorsinc.com
