I have a light with this bulb and ballast. The light just goes off by itself. Do I need a new ballast? I bought a new bulb and it goes off too.

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.

I had the same problem. I replaced the ballast and it took care of the problem. I also discovered the old one had got so hot it was partially melted.

My light bulb did not work so I bought a new bulb. It ended up being the ballast.

You have to remove the electric ballast from the hardware.(cut the wires and remove from unit) Also, the electrical wires from one end of the led's are not needed anymore.

Are they speaking about the little light that is inside the dimmer? If so, mine has lasted forever. I wouldn't know about that. If they are speaking about the bulb that is in the lamp it turns on and off, then that has not happened to me. If my lamp burns out I replace the bulb and it has no effect on the dimmer. I highly recommend these dimmers! Mine is a necessity!

My light recently stopped working after 2.5 years of daily use. I replaced the bulbs but that did not work. Usually this is a sign that the ballast needs replacing. I can't find it however even after removing the ends and looking down the tube. Before I take it apart any further I'd like to know if anyone else has done this repair successfully. I contacted Hydrofarm. I have not yet heard back. Here is there support page: https://www.hydrofarm.com/support

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.

You should contact the company directly. I understand from past reviews that they have good customer service. I have had problems with my light randomly going off!

Jennifer: Kill the power to your fixture so you don't get shocked. Then dissemble it until you find the ballast (which will be connected by wires to the base where you plug these bulbs into. The ballast is probably held in by a couple of screws. Get it loose so you can examine it. In most cases you can find some clues as to its origin. A manufacturer, part number, etc. Write all the information down, then Google it (or your alternate search engine of choice). Oftentimes, simply searching the part number will give you an exact match. If that doesn't work, try contacting the manufacturer of your fixture. Good luck and be safe in doing this.

Check your power source. Make sure it's strong enough. Maybe you just got a bad bulb ! Mine is still working fine.

Mine goes completely off. I can't imagine it is the bulb causing power to stay on, something else must be in play.

Sorry Robert, I don't know about a ballast. Purchased the extra bulb from Amazon, have not encountered the ballast issue. Good luck.

If it comes on at all, it should be wired correctly. The bulbs and ballast have nothing to do with the sensor, which is what tells the switch to operate. I would suspect the sensor may need to be re-positioned to better see the motion.

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.

I purchased same unit. The blue light at bottom would come on when plugged in. I took it apart to clean filter and the clear washer didn't seat properly so I got water in glass and bulb blew out. I purchased 2 bulbs on Amazon for about $25. Put in new bulb and made sure no water could seep in tube and its been going strong for over 6 months.

No surprise. My last one lasted two weeks. These cheap bulbs cause damage to your ballast. Expensive repairs resulted. Bite the bullet and buy the Mitsubishi bulb. Mine lasted for over five years.
