good read on HID lamps

HID = high intensity discharge.

Excellent . This should be required reading for all those considering MH lighting. It would also be excellent reading for those who consider themselves experts.

glad you took the time to read it

I have read this somewhere befor and it is a good write up. the only problem i have with it is that it is an advertising to permote the sale of there electronic ballasts so there may be some scewing of data in its favor like any company does.

but a few good parts

forget it for some reason I can't cut and past out of the document. but I would love to get my hands on a couple of the specialized electronic ballasts they are talking about to test actual output in a nutral enviorment.

also the ceramic MH looks like it might be interesting so I am going to have to dig deeper on that one and see what color temps you can get them in. right now our bulbs lose anywhere from 15% to 50% of there output over there life but we only use them for a fraction of there life so we dont see it. so if ytou are like me and run your bulb 10 hours a day for 1 year you will use up 3650 houre of its life.. mine have a life of about 15000 hours so I am getting 1/5th of the life from my bulbs. so I will probably only experence a small loss of color and output as the major changes will be in the last 1/2 of the buble life.. if these ceramics will only lose 200K over there rated life and only 5 to 10% of there out put that means we will be able to go 5 years or more on 1 set of bulbs... hmm wonder why the fish eqipment people arn't pushing these

but hmmm maybe I will have to buy one of thoes new dynomax ballasts and try it out.. only has a cost savings of 1.4% over the pulse in start up cost one a 300 light system but I like some of the features of it..

I like the sounds of the dimming capabilities.

I did notice they bashed the probe starts pretty hard and worshipped pulse/electronic ballasts, but they sound neat..too bad they cost so darn much. I was lookin at an e-vision 150w dimable electronic ballast, and it was $274

it'd be a great market for you to get into steve if you could design 10000k-20000k ceramic bulbs for all of canada

I also liked where it said if electronic HID ballasts were to run at higher frequencies, the bulb would destroy itself...i thought that would be cool to see.

no you don't read it again it is oposit of what we want. it pounds full power for a while untill the bulb is at full operating temp THEN it dims the bulb. It will work fine for night time but it will look bad for the morning.

so far the highest K ceramic I can find is 4300K

well that's just silly.
