150 watt HPS ($20-econo)

Just got my 150watt hps light from econo...wondering what type of lumen reduction I will get if I use the existing glass globe that comes with it. Any ideas?

Sorry to add but...if I just leave it just as it came, is the heat difference going to be drastic. What I'm trying to ask is, can I just use it as it is without converting to a remote ballast and not worry about too much heat? I will use a few computer fans and an internal fan for circ...thoughts?

I didnt do a remote ballast on mine and its kind of hot. I have that light and 10 26 watt cfls and 2 crappy computer fans, but I can't keep my door closed. I only have to keep it a couple inches open, so its not that bad. I just ordered a 4 in duct fan from htg so I can tell you if that works in a couple days.

Thanks for the input. How big is your grow area? I am also looking into the duct fans...which one did you choose and how much was it?

Im doing a dresser grow so its only like 3 by 1.5 by 3.5, I got the 4 in dct fan from htg and it was 20 bucks. It says its rated at 80 cfm and they say you need to exchange the air every five minutes and this will exchange my air like 4 times a minute so hopefully it will work.

Very cool, I decided to re-wire so I wouldn't have to worry about heat as much. Check it out...ghetto, but it works.

Ya that looks good, just make sure you take that glass off when you put it up.

Im sorry but can you explain how you wired that? when you unscrewed the ballast from the bulb and wired it what wires did you match? and what is the yellow tape you used? can you please provide instructions on how you did this?

Ok, I'll try to explain this as best possible, but it's a little hard to describe step by step. When you first get your light, you will have 3 wires coming out (black, White and copper-ground). These are the wires you will eventually connect to your power source. My first step was taking it apart without disconnecting any wires. When you remove the socket portion (the part the socket is attach too) be sure to note where the black/white socket wires are attached. From the socket, the white wire will be attached to two other white wires (one goes to the igniter-white box and the other goes to the power source) The black wire will be connected with two red wires (1 goes to the igniter and the other to the ballast). If you look in the picture, all I did was use an old ext. cord to make the connection from the socket to these items longer (see Pic 1, the orange ext at bottom of picture)...don't worry about the green grnd wire on this portion. Look at Pic 2, you will notice the yellow clamps...those are connectors for the power source ext. cord. You can see which wires are connected where...BE SURE YOUR GREEN EXT. CORD WIRE IS ATTACHED TO THE BRASS GRND WIRE IN THE LIGHT. Okay...so hopefully you've made it this far. So.....one of the ext. cords using only the black and white wire are going to the bulb/socket portion and the other is using all three wires and is going to the power source.
I will also attach a ghetto diagram to better explain which wires are going where...hopefully it will explain too. Let me know if you have any other questions. REMEMBER, THE PURPLE LINES ARE THE WHITE WIRES.

I know this is confusing, hopefully the diagram can explain it a little better. Please let me know if you have any other questions. OH YEA, I only grow tomatoes...

Oh crap, in the diagram, I have a connector without any wires. In this light, the blue wire connecting the ingnitor and the ballast run through this..you can see it in the pictures.

thanks got it got my all wired up i didnt use a thick extention cord like you did i just used a regular extension cord. Would that be a problem. It works fine just wondering if the cord is heavy duty enough. I used a pc cord as the power source

Unless you got an extension cord so thin it's illegal in the US you're fine.

I am hearing a song in my head reading this post, and it's funny. Bruce Springstein, "Oh, oh, oh I'm on Fire...." Lmao!!!
