Anyone have a LED dusk to dawn pole light?

Another example:
Here's another link from earlier in the thread:
Feit 73995 3W Replacement 5K Non-Dimmable LED Yard Light - - Amazon.com
4000 lumen for $60. Multiply that by 10, 40,000 lumen would be $600.
The link I provided was:
40,000 lumen for $500

Any way you look at it, $500 for that light is not unreasonable.

The only question I have about LED lighting is why wasn't it developed and more widely available sooner. The cost saving benefits outweigh any negatives pretty quick. It is not like we haven't know about them for a long long time.

Who Really Invented the LED?

 

[Sysop]

LEDs of the early 60s (when they first started being produced widely) were dim and limited to a couple colors. They didn't figure out how to make blue LEDs until the 70s, which were very expensive. It took a lot of years and testing various materials for the technology to advance enough to make white LEDs. Even more to achieve the lumens and color spectrum produced by incandescent bulbs. The price per lumen has decreased a lot over the same time. Most of the LED tech advances have happened since 2000.

When you look at the comparable traditional light, the price isn't high; it's average. Nor do I think your passage door LED bulb was built to the same standards as either the halide or LED I linked...
ly.

$500 is alot to spend.IMO You have a link for LED from Amazon, and the metal halide, from Grainger, which is industrial prices and quality.

Me and you are starting seeing eye to eye.
The technology hasn't matured enough, or is not the correct appliction.

I do . I can get a metal halide $75-150.

Reason being: Amazon seems to be where all the other links in the thread are from so that was the "go-to" site. But all I could find on Amazon in halides were the bulbs, no fixtures. I just did a web search and the Grainger link came up. I never looked on Grainger site for a LED... I'm not out to do all the shopping and consumer research on them at the moment...

I'm just pointing out the fact there are some LED alternatives to the big sodium and halide lights folk have traditionally used to light a lot of area; as well as the fact they're not much more expensive than traditional lighting of similar output.

As far as your assertion that because the halide is from Grainger it must be higher quality than something from Amazon is a little silly. Amazon sells a wide array of industrial components, many of the same items as Grainger.

If you do a little reading about the LED on Amazon, the product is designed in the USA and uses Phillips Luxeon LEDs. I find it unlikely they skimped on other parts of assembly of a $500 component and put a 5 year warranty on it.

$500 is also just for the largest of four models on that page. The smallest is still 7800 lumen at 60W and is only $180.

You can spend that much just on a 1500W metal halide replacement bulb, not a complete fixture. I've not seen any complete units at that price.

If you don't like the Grainger halide unit, I came across one at Amazon. It is only 1000W though.

If ya want big boy lights, they're going to be expensive. Always have been.

Do you need 1500 watts, 150 is probably more then enough for most. I have 100 watt. $10 for HPS.

15000 watt huge difference.

Full of ignorance. Story problems are hard for people.

I have no problems with stories. I like a GOOD story. When that proverbial dead horse has been beat beyond recognition, it is no longer very interesting.
