My ballast says Electronic Fluorescent Ballast, RB-CHB 40, class P Type 1. Will the TCP 12537 or TCP 17056-58Q work in this. Just bought a new bulb.

Not sure, your best bet is to remove your old one and take it to a Lamp and Fixture supply company. They should know for sure and if their price is too high then you can always order from Amazon.

This will more than likely work fine, ballasts are not that picky. they sell these at walmart now too for a lil bit more if you don't want to wait.

I have wondered the same thing. I have not tried it because I dont want to waste money on bulbs that dont function with this light. Having worked with lighting extensively through out the years i dont think it will work., the ballast probably wont light them and if it does they may not light fully. If any one else tries it please let the rest know. Sorry this wasn't much help

I agree with analyst below. If the lamp is a Verilux lamp i will require a Verilux (expensive) bulb. If the lamp is from a different manufacturer, the Verilux bulb may or may not work. l'd buy the cheaper Treadmark lamp and get at least one bulb from them. Then try the Verilux bulb. If it doesn't work, perhaps you can return it for a refund or credit. Hope this helps.

I had the same problem and now cannot find a replacement ballast, not sure what else it is. Electrician installed so I keep trying to see if a recall on ballast.

Yes, if you have an hps ballast (I would assume with 90% certainty that your digital ballast is for hps, and a 60% certainity that its a switchable). Either one of my assumptions would mean that yes it will work unless.......................................your ballast won't light up hps bulbs :) (its a joke)

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.

No! Has to be hps ballast. Mh ballast won't turn on hps bulb. But hps ballast will turn on a MH bulb.

Donna, the Keystone ballast KTEB-2C72-1-TP is available the WS is for the circline due to WS standing for "with socket". if you find the Part number you mentioned that will work. let me know if you need any help with finding it. i may be able to list it on Amazon so it would be available through Amazon.

Your existing fixtures work. However they have to be required. I have two types and each set has its own special wiring... And will not work with fl ballast.

the reason for the ballast is to convert DC into AC. So if you're replacing one, as long as it's for a 35w hid bulb, it'll work perfectly.

It will work. Just will not be the color you were anticipating. Side note..I changed to another system my ballasts kept blowing out.

Usually voltage regulation going to the light. Check the volts and if it is on point then it may be a faulty ballast.

As long as your ballast is rated for t-12, takes the 96 inch single pin bulb you should be fine, just not as bright. Remember the T-12 are going away soon. They are going to be harder and more exspensive to purchase down the road.

I think if you have the option to pick just the basic 9006 bulb, try that instead of the HB4. If you don't have the option, I can't really help with this answer. Srry. Maybe someone else can. Good luck.

It is called a "TCP 4001 Hardwire Base for Circline Ballast." I do not believe there is any circuitry in the base. The base seems to just be a socket to feed the 2 pins 120VAC.

Not sure I completely understand the question, but I used it in a unit with two F40T12 48" fluorescent bulbs. Both bulbs start off of this one ballast.
