High-bay/ industrial LED lighting

Hey all,

I'm a long time lurker, and I hardly post, but I have seen something that might pique the attention of a few peeps around here.

http://www.cooperindustries.com/content/public/en/crouse-hinds/products/lighting/led_luminaires.html

Maybe some of you have seen these, maybe not; but I can assure you they are f'n bright! (The mine i work at has been replacing hid's with 200watt versions of these). I see on their website that they have a 3000k warm white option and a 5000k cool option. I haven't found much for useful details yet but I thought I'd take a shot in the dark and see if anyone has looked at these..

Thx!

Yeah i've looked at them (similar to these).....Thatz as far as i got...they are way out of my price range and not practical for my current setup....

You going to get some and demonstrate their awesomeness for us...?

Thx for the quick reply Chron! What was the price that you saw? I am looking to replace my HID with LED, but like anyone else I want bang for buck so I am going to DIY my own setup..

P.s.- Good gob Chron on your grows, I have been spying on you and a few others and it has inspired me to switch over. Keep up the great work!

All good. Thanks for the complimentz.....

I dream of this....^^^^

But i would split it up in 100w lights so 4 of them (or more)

I cant justify that price at the moment....so i'll just stick with my shitty floodlightz....they havent let me down so far..

Those are definitely cool! It seems that there are no diminished returns there considering that its a 400w- 40,000lumen (if it actually performs as advertised)... They appear to be passively cooled, but I bet a piece of duct that fit over the heatsink with an inline fan would cool it really well! Interesting indeed!
I can't help but wonder what it would cost to DIY a setup similar to those..

Well the mulitchip LED's that they use are reasonably priced...

reflector is cheap...

Driver is reasonable...

I guess that the heatsink is the expensive part on this setup...

I took a quick look at the 25000 lumen 263 watt one. Here is the skeptic review for industrial lighting purposes. They claim "Cooper Crouse-Hinds’ LED luminaires on average consume 50% less energy than HID luminaires". That makes it sound like it doing the same job using half the energy but it is not. The only reason it uses 50% less energy is because it is running at half the wattage and putting out half the light or less.

Taking 10% ballast losses into account, a $15 400w metal halide bulb provides 89 lumens/watt. A $20 400w HPS provides 125 lumens/watt. This LED claims 100 lumens/watt but probably costs in the range of $1000-$1500.

It says the heatsink adjusts to make sure it doesn't exceed manufacturer specs. Makes me wonder how hot are they running em. Did they measure lumens at a typical running temperature, probably not. They lose 20-30% of their lumen output when running at max 150c. In that case they would be 70-80 lumens/watt which is less efficient than HID and costing 10X more.

All that said, the LED does have some advantages. In huge warehouses they can be used with motion sensors and kick on and off with instant full brightness as many times as necessary with no harm to the lamp, unlike HID which just burns all night. It directs light to the target better than HID or fluoro. Finally the lamp will last longer although if running at 150c, not much longer.


As far as the LEDs ability to grow weed: 600w HPS kit cost only $200 and outputs 150 lumens/watt, nuff said.


Obummr must have subsidized this LED for Cooper with taxpayer money

Hey Supra, I found a price on their website that lists the 25k lumen units at a cool $2300... LOL!!

Maybe I will find one in the trash bin at work in about 10 years..haha

I guess there is no way around doing a quality DIY unit if I "need" to go the LED route..

Thx guys for your input on this matter!

I've been eying these style lights for awhile. There are a few companies around that have high bay LED lights, and among many of their uses, I keep thinking about using them on cloudy days in a greenhouse.
It seems like most of the fixtures are a bit large scale for the <100W/fixture users, but they don't advertise PAR range or umols at 2ft or less. I'd have to look into output angle too, but I'd think these type of fixtures would have awesome penetration.

The high-bay lighting is what inspired me to start using the smaller flood lamps now available at DIY stores, The White LED IMO works very well

any good ?

wow just relize how ild

You can apply for rebates. Here is Australia, the government is offering rebates on LED high bay lighting upgrades.
