I have several of these but one has quit. Changed photo cell& bulb but nothing. Read where "ballast" could be bad. Does these lights have ballast

They would have to have some type of ballast system to power the light. I would just replace the entire unit. There cheap. Mine seem to last about 3 years but i only run it on the weekends. I want to update to an LED in the future. Good Luck.

Yes, one of our lamps flicker every once in a while, but eventually turn on. We bought the last lamp from Amazon for parts. We have six of these and the lamps fail often. There is no customer service for parts. I call the number listed, leave a message, and no reply.

Typically when a fluorescent ballast is failing you will see the light flickering then eventually it goes out. There are two plastic clips that hold this ballast in place and pins on the ballast that plug in so if one of those clips is broken the ballast could be hanging and not making good connection on the pins (the clips broke on mine that I had to replace). There could also be a component overheating in the ballast causing it to turn off. The short of it really is if you've replaced the bulb and you know the switch and connections are good then there isn't much left other than the ballast.

This is a good ballast unit. I haven't had any trouble with mine, however it is something that can break down. The fan needs to be on to cool the unit. Have you plugged in the light swvith? The plug goes right in the front . If after you plug in your unit and it does not work you need to call the company you bought this from and ask for a replacement. Hope this helps

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

I bought my light set thru amazon and a couple of fuses were constantly popping. I called Fotodiox and they had me send them back. They sent me some replacements but I had to keep calling them and asking them where my lights were. Be sure to keep your tracking number handy when you ship them back in case you have to babysit like I did. Check your fuses first and make sure they're good. Also, double check your power cable connection.

Check to make sure you have power to you light fixture. Your ballast needs to be replaced.

No. It's not the bulbs. It's the base. For some reason it shorts out. I've found it happens if you generate static shock while touching the lamp.my initial 2 went out with in weeks. (I bought 2) just had a replacement go out last week. So will be calling for a replacement again.

this is a ballast/inverter problem related to florescent backlight, period. you can either replace entire LCD unit or exchange for another model/brand or same model and hope the next set is better--not all will do it.

Check to make sure it is the right one for your bulbs. If it isn't putting out enough voltage to fire the bulb and then maintain it, you may have the wrong ballast or the wrong bulbs. That's what happened to me....I ordered the a D2R bulbs when I really needed D4R. Still have them if you need D2Rs New...give you a great deal on them.

I've tried these bulbs in several different fixtures, including the fixture from the company. 6 bulbs in 8 months. Last replacement bulbs, one busted. Gave up. I now use plant bulbs from Walmart that are great. Plants thrive under them. The city you live in might have a nursery that carries them. Agrolite can provide you a location. Me; I'm sticking with what I'm using now. They last! Hope this helps my friend. Also; their fixtures are weak. Ballasts burn out quick. They sent me a replacement fixture that was not shown on their ad. The " new" fixture had "shop lamp" marked on it. So I paid close to $40 for it. Same fixture at Walmart, Home Depot had same fixture for 19.99. Buyer beware!

This is a photograph of the light bulb. It worked in my fan. The ballast is a different issue. Sam L.

I had problems with my OPT7 55W system. Problem 1: Bad Ballast. Trouble shoot by switching ballasts & lamps to detemine if this is a problem. Contact Opt7 & they will send a replacement. Problem 2: Power & Ground from existing wiring harness to Ballast. Eliminate as many connectors & splice wires directly to each other. Install relay to get power from a reliable source. Ground negative side to reliable ground point.

Yes, I did change the battery in mine because it wasn't working. I have two lights and one quit working. I bought replacement batteries and changed them with no problem, but the one still didn't work. Unless you know it it the battery for sure, I would not waist your money on new batteries if it just doesn't work.

If the dimmer switch is in the correct position, and the bulb is dim, replace the ballast before is ruins your bulb. If you grow what most people grow indoors, even though the Quantum is covered under warranty, I would replace it with a Phantom, which is more money, but it won't ruin a crop! I learned my lesson 3 times! Good luck!

I have two sets of these lights. I have had them for about six months and use them constantly. They work great. I've had no trouble with them. Either you got a bad set or there is a wiring problem. The odds of neither of them working is slim so I would recheck the wiring. I hope this helps.
