I plugged it in, I can hear the fan in the ballast...but no light. Is there a switch I am not seeing? There weren't any instructions in the box.

try using a different light ball because when I got mine one of the light bulbs did not work
1161186
No, just the one switch that allows you to pick between 50%, 75%, or 100%...There is a hot lamp protection built into it, so that it doesn't illuminate a hot lamp immediately in the event of a power failure. If you powered it, then unplugged it for second and plugged it back in, you may be in that hot lamp protection mode, or your bulb might be bad. Leave it on for 10 min before giving up on it. If your system came with 2 bulbs, try the other bulb.

My guess would also be the bulb, try both and if it still doesn't work maybe you could take it to a grow shop and have them try one of their working bulbs in it.

Check the cable from ballast to hood. I had one that was damaged. I gets damaged from the opening.

This unit is sold with lower quality bulbs, in fact one of my bulbs was not working ....did you try the other (included) bulb?

It should just light up. Is the light screwed in properly? It could be a faulty light bulb. Mine fired up quickly.

CHECK all cords make sure you have right power and switched right then 100%to start.If that don't work send ballast back. they have bin really good replacing bad or defective.

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

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

I used an electronic dimmer switch and it works like a charm I got mine at Ace Hardware for less than $20. Remember you are controlling the power to the Ballast not the Lamp

No those were the only instructions I did and it came on. You might have gotten a blown out light. Try plugging it in where you know electricity is working to make sure it's not your outlet. If that doesn't work definitely get a return label for a new one. Hope this helps!

it's probably the ballast sounds like you have done everything else..... good luck

Yes I did, and they sent me a new ballast but still didn't work. Even sent me a new kit with no luck. Great customer service, but inferior products lately.

I had the same problem. I replaced the bulb. It works for a while. Now it is going off and then back on again. I believe the ballast may be bad.

This happened to be but it was because I had not connected the light mechanism. I wanted to see if my electrical connections worked before I installed the light housing so I turned the fan on and click, nothing. After I plugged in the light mechanism the fan began to spin. Btw, I never used the red wire coming from the house....hope this helps.

No noise nor light. It's been awhile, but I believe a small indicator light (like power on) did illuminate.

Sorry, Ryan, no clue. Is the socket making firm contact? Do you have a dimmer on that light? Beyond that....

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 .

The fan should come on when plugged in. Return it before it before it over heats and isn't repairable.

The internal fan is broken, same with mine. Opened it up and its a cheap computer fan. I replaced it for 4 dollars at a computer store and it works. If you're under warranty, send it back or take the risk and replace the fan.Good luck

Unfortunately I have had no problem with my HID ballast. Try contacting the manufactor.

Ballasts do not determine kelvin temperature (or the color of the light)......it's the bulbs :-)

I would send it back. I have had mine for some time and have had no issues with mine. Sounds like a bad light sensor. Good luck.

You must remove the ballast and wire the hot and neutral directly to one of the sockets. The other end gets the wires removed.
