To LED, or not to LED, that is the question...

[grsthegreat]

also consider induction lighting. im seeing alot of this in commercial/industrial work. not sure if its made its way into parking lot lighting though

I am suprised at that. With you seeing them here with the mercury and all?????

I thought that is why they were phasing out the MV lights and going to HPS and MH, now we are back to mercury??? And outlawing incadescents for products like that???

Dont get me wrong, I like MV lights and dont have any issues with using mercury. It just doesnt make any sense though:confused2:

IF your looking for Lumens in a LED, The company I mentioned before http://www.ledroadwaylighting.com/ Has a 14,350 Lumen 200W lamp available in their 96 LED fixture. Again, no idea of cost, but it's their largest unit, so probably not cheap.

I do not see why anyone would automaticly replace the capacitor and the ballast.

Seems expensive to me

I have about 200 400 watt MH fixtures in my plant and less than 10% has a ballast fail

The ones in my first line are parking lot lights.
I'v spent to much time going back to replace the ballast after the new lamp higher current finishes it off the old ballast so it's new electrics in the old sheet metal and a lamp. There is only about 20 fixtuers in the parking lot.

The 700+ florescent fixtuers in the our plant that runs 7/24 and and they wont shut the machine down for a lamp change over the machines so usually the ballasts are bad too by the time we can get to fix them.

We have 6-7 complete fixtures spare and ready and swap them out when the machine is down.

In between the machines we can keep up with them they get 6 new lamps when we do them because of the complaints that all the lamps aren't the same brightness and are then back in a week or 2 changing the rest in the fixture.

i used to have to do alot of work in buildings that ran 24/7, and swapping out fixtures and or equipment SUCKED. One company actually said that if we tripped the main breaker someone better be dead..... as it would cause up to $1,000,000 in product destruction (pharmaceutical company) due to loss of positive pressure system and their associated alarms.

i HATED that job. was glad when i quit that company.

Induction lights do use mercury and i too was surprised that there so popular; however the power producers here in Idaho still give refunds if we retrofit them. This technology is older that LED, however they do produce alot of light output per $ of power used. no wasterd power in heat production.

The best option I have seen so far (still waiting to see some in action) were some from DIALIGHT Dialight - Street Lights costs were up there close to 700~1000 per but very long life.

had a guy in to get some info for the Explosion Proof 4 footers. they had a shake up in the sales department recently but you can buy them through many locations. ALLIED is one I would suggest.

MV are best OLD solution (high lumen output, long life good color quality ect.)

MH not fond of the brash light also ballasts seem to have short life with them as I think they heat up a lot more. CAPS also pop in them more regularly.

HPS light is ok at start but fade out fast. yearly or so replacement is normal it seems.

I work at a semiconductor mfg plant. For us it's about a million an hour. That's kind of rough since there's two types of cost. There's loss of production and then there's the cost of the equipment that needs to have contaminated parts replaced and then restarted. We do have insurance and most tools have two sources of power. Every other year the insurer makes us replace the breakers for each tool.

One of the tools has 4 lamp buckets that have 14 1000w watt bulbs running at about 50% power just for the heat, we have about 50 of them. They are always on 24/7 unless being repaired 365 days a year. That's just one type of tool out of about 50 types. I didn't even talk about all the vacuum pumps.

I have a feeling when LED matures it'll just mean they'll all come from China, and like most stuff from China, will be very low quality. Like CFLs.

 

[grsthegreat]

hate to break the news to you, but not all chinese stuff is cheep crap. they product the quality that the client wishes to be produced. if you are only willing to pay 10 cents for a dollar product, there only going to make a 10 cent item.

they have the ability to turn out some **** fine products

Agreed:thumbsup:

Also, a previous post mentioned the 200w LED and 14,xxx lumens. I think that sounds kinda low for the lumen output???? I aint sure but isnt MV and HPS BOTH produce more lumen per watt????

Edit...just looked.

A 100w HPS is 9500 lumens. So thats 95 lumens per watt
That 200w LED @ 14000 lumens is only 70 lumens per watt
A 175w MH is 12,800 lumens= 73 lumens per watt
And suprising A 175w MV is only ~8000 lumens...or 45 per watt

It seems that led ISNT the post efficient use of wattage. Add that to the high cost and poor light dispersion, its no wonder why they arent popular.

They do make gread flashlights though:thumbsup:
