Can be directly connected , put a small fan on the backside of the internal ballast . The vents on the opposite side the light is on , it helps .

Sorry for the delay. I couldn't remember so had to find the instruction and look it up. As far as I can tell the answer is no. However, the dimmable feature has become greatly appreciated. The lights look very nice dimed down. When one of them kicks on I know someone or something set it off. We replaced five outside lights with these and after a summer have them tweaked to where we like them.

I'm not sure... We've never had that problem. Could be in the ballast. I suggest contacting the manufacturer.

It's just 1 ballast. I'd recommend looking at www.theretrofitsource.com their ballasts are a bit more expensive but are much better quality

All halogen bulbs are dimmable, while not all LEDs are dimmable...so yes these are dimmable

Hello, sir, sorry, this is a dimmable bulb, if you install it without our special driver, it cannot be dimmed normally.

Mine does not remember the last dimmer setting. It normally goes on about half of full power.

No, it is not dimmable. It radiates such beautiful light, you may not want to dim it anyway.

Not dimmable. You can put a smaller watt bulb in so that it's not as bright, however.

600 watt is magnificent with a dimmable ballast you can cover such a wide range of everything. This is definitely not a hardwired ballast

It's just a light fixture with three sockets. Whether or not it's dimmable is entirely dependent on the bulb you screw into the sockets. So yes, it's dimmable.

I bought this for a 4 ft. Fluorescent Light for an aquarium, which is why it's waterproof, this one will not work for dimming. They do make a dimming Ballast which will work, but it's dangerous and should be done an electrician.

The dimmer only saves the last percentage level that it was on. So if you set it to 50% and turn it off, it will return to 50% when you turn it back on. If you increase from 50% to 100% and then turn it off, it will not go to 50% when you turn it back on. These dimmers are meant for home automation scenes, so you can achieve the effect you are looking for by using a remote controller.

Yes, it's the ballast warming up. The sound should diminish somewhat but will still be hearable if you're real close.

I ask my husband. He said there is no electronic ballast. He would know since he is and electrician.

No it is NOT dimmable and contrary to another answer it CANNOT be dimmed with a separate transformer. You can't guess at these things. If you don't know, don't answer the question. I did try a separate dimmer but the light dimmed about 5%, flickered, and then went out. It is meant to be used as is. If you would like to know why some fluorescent lights can or cannot be dimmed, look it up on the internet. You can find some nice technical explanations.
