how does this ballast fit inside of a 8 inch T9 blub

they do not go inside the bulb. the bulb plugs into the ballast socket, the ballast may mount inside of bulb circle , but it should mount to the light frame.

it's been a while but this ballast is a lot smaller then the one that was in the light fixture, and it worked just great. Would buy again

Terry, this. Ballast works perfectly with two tubes of 40 W, it is also very cheap.

Sorry my reponse took so long but I broke my phone anyways 175 watt metal halide is what this ballast is set up for beware purchasing make sure it comes with the bulb and for added safety u should purchase the protective lens from them also to make it safe or else one drop of water can rupture the bulb

The light plugs into ballast not into the wall outlet. If you purchase the proper bsllast, it will fit perfectly.

Be careful that the base matches. There are several that look alike. Some have ballasts in the bulb others have the ballast in the socket. Mine had four holes in base but two holes were blocked so that the 4 pin bulb I bought didn't fit so I had to send it back and then the replacement only lasted one hour. After buying four bulbs and they only lasted a short time, I gave up.

Check the cable from ballast to hood. I had one that was damaged. I gets damaged from the opening.

Can't say for certain about this particular ballast, but my experience with other fluorescent fixtures is that F34 bulbs will work in place of F40 bulbs. Just be sure you are using T12 (1-1/2" diameter) bulbs and not a T8.

Nope, I'm sorry but it really has to be T8 48". You can check out this one, it's what I'm using for this fixture and it's been working great ever since. Hope it helps! (Case of 10) F32T8/SP41 Linear Fluorescent 32-Watt T8 FO32 741 Light Bulb 48"

I used the Apex HID Xenon Conversion Kit "All Bulb Sizes and Colors" with Premium Slim Ballasts (9007 (HB5) Single-Beam, 8k ice blue and it worked great but you don't have to stick to this brand just as long as you have the right bulb size you should be fine.

The ballast you listed is for circleline. that type of tube has a special plug with four pins bunched together, while the 48 inch replacement ballast for two tubes has four clip in sockets for the two pins at each end in the long tubes. Be sure to place sockets in their correct color codes alignment as in the instructions.

it fit although it was about 1/8 of an inch longer then the stock light that came with the tank. its just a bit tighter in overhead.

It is a T-9 size bulb. The number in the bulb size stands for the diameter in 1/8ths of an inch. T-9 = 9/8 of an inch or 1-1/8 inches in diameter.

They will FIT, but they are designed for electronic ballasts, and the old T12 ballasts will burn them out much quicker if they work at all. Plus you won't save any money on electricity if you keep the old magnetic ballast. Not a good idea to swap them without at least putting in a T8 electronic ballast.

I am not sure. You should be able to get the Manufacture number off the ballast in there now.

I'm using a 6 bulb t5 . It fits between the frame rails. It's about the same size.

Daniel: please read the review I wrote on December 6 2011 "Excellent electronic ballast for one F40/F34 T12". It describes the slight difference in wiring that I encountered on that installation and the wiring conventions I followed. Perhaps it will help.
