Has anyone purchased any of those 110v LEDs for home use?

[heliyardsale]

I'm talking about the type that DE has, they come in 36-48 and higher LED flavors. I bought one of these types off e-bay a long time ago and it was junk. Crappy light output, very blue in color. I was re-thinking trying them again, Mainly for a light on the side of our house that we always leave on for the dog and cat. They might be good for a SHTF event when used with an inverter.
Any input or reviews on the DE 110v screw-in LED bulbs?
Thanks,
Heli

I have a low power one (10 watt incan comparable) on order for use as a night light in the room our hounds use to exit via a dog door. It is actually a flame tip decorative type bulb and it is supposed to be a warm tint. The company actually provided the color temp numbers. I will try to find this post and let you know how it works after it arrives. If it works as promised it might be worth checking their site as they provided technical information on many of their lamps that "should" help eliminate surprises. They do offer higher power LED 110 volt medium base bulbs as well as lower power ones such as I ordered.

Hello.

I've purchased several form goldeng.

I make kits paticularly for hunting camps/challets. Using a generator or those 12vdc inverters (for 110v in the car) and standard 110v sockets.

If your celling is high enough 10 feet (at least) then the spotlight version led's bulbs are good.

Any lower and i would recomend the flood light versions.

All in all i find these led bulbs a mixed blessing. Having to have an inverter (inverter in the bulb itself) and a-lot of resistance (step down) does generate a-lot of heat and a waste of energy.

It would make more sense to have a single power converter for the entier lighting system (ex: 12vdc). The same systems used by dedicated solar power users.

Less wasted energy.

However these bulbs are a wonder for plant growing. You can easily get coloured ones (red or blue) for about 10-15$ each instead of paying 200+$ for a plant kit with the same 3 bulbs.

If you wish to use these led bulbs as a relaible closet, or infrequent use lightsource then they are very good.

Be certain to give these bulbs plenty of air (space) to keep cool.

I agree with Northernflame, I have used the 12v versions for car and a solar powered system in an out building, much more efficient. You can get them with 3x1watt crees for 170lumen (also avalible for 240ac and I guess 110), or with 3-18volt dimmable luxeons.

Household circuits have enough juice to start an electrical fire, so any equipment connected to them has to be approved by the powers that be (different for different jurisdictions).

In Canada it is the law that all mains connected equipment has CSA approval or the equivalent.
In the USA AFAIK it is not a legal requirement but Insurers can get very grumpy (and downright non-cooperative) if you connect non-listed gear to household circuitry. Especially if it causes a fire.

Here are the UL listed bulbs I found so far.

If you don't like the blue make sure you buy bulbs with colour temperatures of 6500 or less. If colour temperature is not ststed assume it is too blue.
Warm white bulbs are available though they are usually 20-25% less efficient than the cool white. Some 5mm based warm white have a puke green tint. Warm white luxeons are probably the best for colour.

I suggest looking at low wattage CFLs. Ikea have them as low as 4 watt.

I have built a 10 Watt Cree down-light for a can fixture in my office.

They have a whiter color than the 5mm types.

Adding this one...

Mainly for a light on the side of our house that we always leave on for the dog and cat.

Hmmmm. I'm not really sure a dog and cat needs a light left on...well, not the cat, anyway. Aren't they rather known for their ability to "see in the dark?" :thinking:

I'm afraid my 48 LED DE light started out great, but after a week (about 2 hours total use) half of the LEDs are out....:thumbsdow

LMAO, actually its to save the dog from the cat... Our cat waits outside near the doggie door and nails the dog everytime she comes out... This leads to the dog barking until someone comes down to shoo the cat away. Our cat is one mean mother F@#ker. He kills everything including weasels which are tough mother in their own right. Its for our old half blind and deaf dog, whom really needs a Cree headlight...

Thanks for the heads up. Sounds like the LEDs are given too much current. I was thinking of getting one just to apart and see how they are made and how much current they are pulling.

Any idea idea how the leds are connected up to each other?

Thanks
