Skip the CFL's: The $20 150w complete HPS with ballast and bulb Link

well 150wt hps doesnt really cover a lot of space so flood or spot is a matter of personal choice. But I do recomend augmenting the 150 with a couple of cfl s if you are going to veg under them. the cfls will help even out the light spectrum. nott so much more intesity but it helps to provide a healther veg spectrum.
in a 2x2 ft space using 6 inch 1 gallon pots you can start upto 9 plants but i would use no more than 4 three gallon pots for flowering.the three gallon pot will give you a decent yeild upto an oz per plant when you get it dialed in.

I don't think those are wired safe either, but the part I'm noticing is you aren't using wire nuts either. Electrical tape is used in combination with wire nuts, not on it's own. Where you've just wrapped the wire will eventually become resistive and heat up in use resulting in a fire.

I don't know if it makes a difference without ground other than say electrocuting yourself trying to put the fire out.

They aren't my pictures, but you are forgetting the wires could be soldered together and you wouldn't need wire nuts just some tape.

Also whenever I'm around a circuit for an aquarium, a grow, in the basement, I like to run a GFI circuit so the grounds you are worried about wouldn't matter.

Oh yea, ok. GFI, I hadn't thought about that, good idea.

i was just trying to look out for u guys lol......but i wouldn't mind dieing in a fire fed by my weed...lol..imagine how blowed you'd be. lol

Here are some pics so everyone can stop posting that for $20 you only get a bulb.....

Well actually you get a ballast too. Its built in; The ballast is just what converts to electricity to the right amount. All you have to do is get a power cord of some kind and connect the wires. If you just took a plain bulb and connected power to it, it wouldnt work.

i posted this light back in august since you couldn't find the original here it is https://www.rollitup.org/indoor-growing/101214-very-inexpensive-grow-light-20-a.html

In response to a few people thinking that the more lights you have means more lumens you have is simply not true. Lumens dont add! This is false info that keeps getting reposted.

The lumen figures cannot be added and result in a meaningful figure. The lumen is a measure of intensity. Putting one lamp next to another does not make either one brighter. If you have 2x 1500lm lamps next to another, the brightness is 1500lm. If you are illuminating a space with a 1500lm lamp next to a 3000lm lamp, the intensity is 3000lm. The distance from the lamps to the lighted surface will determine the lux (lumens per sq metre) applied to the surface.

I think a few people have posted this light. You're like the 3rd person to step up.

Anyway lumens do add up, at least according to the sticky post "Lumens, Lux, and adding it all up" which says quote:

"What this means is that if you put two lights the same distance from a point, and each light provides N photons per unit area at the point, with two lights you will have 2N photons per unit area at the point. Because intensity is a measure of the number of photons per unit area, the light is twice as intense, whatever unit you choose to use. Twice the lumens, twice the lux, twice the footcandles."

It seems you're wrong on that point.

i just got mine today and this thing is heavy ha. So i took the cage off and and glass cover (would this keep heat low if i kept that on?). Is there anything else i can do to it so that it not as heavy?

and...

since this is a smaller hid can i have it closer that 2 feet from the top of my plants without burning them you think. im goin to have a 34.5 cfm pc fan blowing adjacent to it, and another fan on the floor blowing toward the ceiling of my 2x2x5 foot box.. im hoping that i can get it closer to the plants so they get the most out of the light.

that sound good?

i got mine too, and though wow, they are heavy......as far as how close to put the light.. Place your hand on top of the plant under the light...if you can handle it comfortably, then so should your plant. I dont think there is a way of making it lighter, and doubt keeping the glass on will decrease heat. 2-running in a grow box was at 115 degrees! you will need a cooling fan of some sort




Peace

ya im goin to have the 34.5 cfm pc fan on the bulb and another 80 cfm fan for exhaust

Mount horizontal with homemade batwing reflectors for the best result. No keep the glass off, I don't think it will help but you can try both ways later.

Those lights should be able to go as close as 4" or less from the tops of the plants. I run 250's 4" away, but I do have a good fan blowing on them and you'll need a fan blowing on the bulb to get that close, or a cooltube.

If you want them lighter you'd have to remote mount the ballasts, which is a good idea actually if you don't mind the extra trouble. That lets you remove a large source of the heat from the grow space.

Lastly you're not running 300w of any type of light in a confined space without ventilation, it's just not gonna happen.

Anyone know how to make a remote ballast with cheep supplies for this light in particular? It would make my closet alot more functional, otherwise im going to have to use brackets to fasten this thing up and its not gonna be adjustable. I'm pretty handy but don't really know where to start with converting this into a remote ballast. Any point in the right direction would be great.

You would be disconnecting the bulb socket from the rest of the thing and splicing a longer piece of wire between the socket and ballast. That's all. You'll want some wire nuts and a piece of extension cord or other electrical cord that's thick like an extension cord.

Two wires, snip them, and extend them with the wire nuts and longer cord.

Would this light work in a DIY cooltube setup using a BakeARound?

Not sure what your question is but it sounds like a pretty good plan you have worked out to me.

im waitin on 2 of these mother fuckers. like50 bux with shipping. cant get any cheaper than that. good looks for the site.

If i buy the $20 HPS, could I remove the aluminum housing and the glass cover; attach a Bake-A-Round; clamp on some dryer duct with this fan inserted, run the ducting up through the ceiling of my growspace and attach Zen's DIY carbon filter on top?

Yes, good plan.

if a 1000 watt hps system with ballast is $300 give or take and produces 100,000 lumens, and 10 150 watt setups are 200$ wich will produce 1500 watts and around 130,000 lumens... correct?

That $300 light would cost less to run than 10 150w fixtures by far, but I don't know maybe you could cover more area with 10 of these if you're growing for profit __and can recoup the electric costs___.

It would have to be for a SOG or similar, these don't have the penetration for really large plants like bigger lights do.
