It does not require a ballast,just hang it,then just plug it in,their is no switch,so to turn it off,it must be unplugged,as far as a comparison with the 125 watt cfl,i do not know,i have never seen the 125 w cfl before,but i tell you this,hps bulb it comes with is very bright...

Nope no ballast just plug in a regular outlet and your good to go. compared to a cfl just depends on your needs and situation. if you want better light penetration I'd say the hps butifyou have to keep temperatures down I'd go cfl. this hps has a bit higher wattage so it will increase on energy costs but very minimal. overall it's a great light with great results in smaller growing areas. Keep in mind also that this is used for flowering and not vegetation. Depending on which stage your plants are in you'll want to consider that. Hope this helps.

the ballast has to be HPS and wattage compatible. if you can afford it, the best is the dual arc 1000w

Please look inside cardboard tube for instructions, because one company you wire only one end and there you wire both ends. YES you remove the ballast, because it is not needed. I have install 10 light fixtures and ordering more. Some show the wiring on the label at one end of the tube which is were you connect the wires.

That is 100 watts per socket. But since 100 incandescent are extinct, I've been using 60's and it looks very nice. Now they're going extinct too. I hate CFLs. Poisonous Mercury in them.

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

It doesn't need one, it's LED. Only Fluorescent requires the ballast. Just disconnect and toss the old 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 had mentioned in a review that I found the ballast of this bulb to be sub-standard and it began failing on me within just a few months. If you still want to give it a shot, I don't see an issue with it being mounted over a fish tank, as long as you have enough space. Check out how big a 75w equivalent CFL is at your local hardware store and see if that'll fit. These things are almost as big as a 12oz can.

No, you have to get a socket with a 3 prong plug that is compatible to the ballast, which usually has a 15ft cord. This socket is made for mogul base cfl's.

The results with the 450W LED are very close to the results with the 1000 W HPS. The LED runs much cooler also. And no ballast is needed for it. Also electric costs are about $30 a month less. For me, it's a no brainer, unless you need the extra heat from the HPS.

This kit only has the bulbs and some wiring. The ballasts are not included. There are several other kits on amazon that do include the ballasts. Hope this helps!

Yes. This bulb does need a ballast. This particular bulb is meant to run off of an 400 watt high pressure sodium ballast with an S51 mogul socket.

e39 cfl (ballast inside bulb) you can run the bulb with a e39 socket and plug (no ballast needed) . I hope that helps.

No. The max bulb it supports is 600watts. You need a 1000watt ballast for 1000watt bulbs.

No. It is LED's. Thre is no ballast as the original had. Much brighter and easy to install.

Sorry I returned this lamp due to shipping damage, but if memory serves me yes you can use a smaller CFL bulb in this fixture equivalent to a 100 watt incandescent. Hope this helps out!

you don't need one. Plugs right into regular socket. Doesn't need ballast or reflector. Worked well for me....for about two years...than started losing lights. When I tried to contact company....I found them out of business.
