hi guys just *found* this bulb outside in a Sign , figure it might be useful , anyone know what it is????? leemmmeeee know
sorry forgot to upload:P
looks like a mh not totally sure tho
Yea MH seems right but that's kind of a bad picture so what do ya do????????????
would a MH bulb be good for veg?...
Yes MH or multi vapor is the only way to go for veg. Blue light builds chloroplasts while yellow light converts them into sugar and starches which the plants use as food. The hortilux ace is the best MH I know of. All depends on the spectrum.
Here is what the sun has...
ci = 3.14814814814814 (refer to GorillaGrow.org(anic) Home of Organic Chemistry Homepage to see more)
100 / ci = 31.764705882352941176470588235296 or A
100 â?? A = 68.23529411764705882352941176471 or B (%yellow)
B / ci = 21.674740484429065743944636678203 or C (%blue)
B + C = 89.910034602076124567474048442913 or D
100 â?? D = 10.08996539792387543252595155709 or E (%red)
________________________________________________
Three primary colors.
Spectrum 360-720
This gives three groups of colors with a 120 nanometer gap each group
The mid point would be half way through giving the first color blue at 420nm.
We would simply add 120nm to get the mid points of yellow and red.
420(blue) 540(yellow) 660(red)
Green is 425 nanometers

.6823529411764705882352941176471 x 540 = 368.47058823529411764705882352938
.21674740484429065743944636678203 x 420 = 91.03391003460207612456747404844
.1008996539792387543252595155709 x 660 = 66.5937716262975778546712802762
526.09826989619377162629757785394 is the total. 525 nanometers is green.
So basically 68% yellow
22% blue
10% red
Degree kelvin is an average that can be anything really. You need the CRI or color rating index
If you have a ruderalous auto flowering strain you will need to increase the blue spectrum to avoid flowering. With a lowryder I would use a hortilux blue.
You do realize that you cant just take this bulb and put it in any old light socket right? You need a ballast for this if it is indeed a Metal Halide.
You mean you stole it? GOOD FOR YOU. Now go put that fucking thing BACK.Quote:

but yah... its to fat to fit into a regular socket .. sooo i was wonderin if there was a way to hook it u to just plug it into the wall??... or not??
Unless you know anything about electricity, no.
And even if you know something about electricity, no. Like Ganja King said, you need a ballast & socket.
You need to know WHAT KIND of ballast to buy too. MH, MV, or HPS all operate a bit differently.
If it is from a tear-down, ask the contractors if they have the rest of the light. Well if you feel safe doing that.
I recently scored 4 HPS 250 ballasts from a construction dumpster, and asked the contractors if they had the bulbs- yup! They gave me 6 of them, all boxed up, because they had to be recycled seperately!
This to me is the best part of legitimately scavenging!
