You want the HLC3 by C.A.P. They run about $100
The HLC-3e by Custom Automated Products protects your garden from overheating and your light from Hot Starts". The HLC-3e constantly monitors your garden temperature. If the garden exceeds the temperature that you have set, the HLC-3e turns off your lights so that crop damage will not occur. It then turns on the "Temp Exceeded" light to let you know that an overheating situration occured. When the temperature returns to normal, it will turn your lights back on.
The HLC-3e also constantly monitors the power going to your light. In the event of a power failure, it will not allow the light to restart until 15 minutes after the power is restored. This prevents your light from attempting to "Hot Start" your bulb, preventing bulb damage and increasing bulb life.
The HLC-3e comes with a 15' remote temperature sensor. The HLC-3e is rated at 15 amps @ 120 volts. 3 year warranty.

you could use a simple 120v home thermostat for a baseboard heater
Simple,
You need
1. 1 attic thermostat, they keep it near the attic vents and roofing supplies.
2. 1 5 Amp or better rated fan speed controller. In the ceiling fan section
3. 1 2 recepticle gang box
4. 1 Male plug
5. 1 switch/outlet cover combo
6. 1 duplex outlet rated at least 15 amps
7. A few feet of minimum 14g wire. I just had some 14/2 w/ ground laying around and i used the male end of an old extension cord for the male plug. You could probably get a cheap 6' or so extension cord and use it for your wire and plug. Just make sure it is rated at least 15A.
The speed controller and thermostat both have 2 black wires coming out of them. You take your Hot (Black) wire from your plug and connect it to one black wire each of the speed control and the thermostat. Then connect a piece of insulated 14g wire to the other black wires from the speed control and thermostat. Connect the loose end of the 14g wire into the "HOT" side of your outlet. The white (Neutral) wire from your plug will connect to the "neutral" side of your outlet. The outlet is marked so it is easy to figure out. Then connect your ground wires. Then put it all together in the gang box. I fastened mine to a piece of 3/4" plywood to keep it all neat. The photo has different parts but the same wiring is used. I just put an outlet on mine for ease of operation. Any fan I plug into that outlet will be run by the speed control/thermostat. In case I needed another fan. Hope this helps. If not, just let me know.

The One from Home Depot only handles 5 amps. The C.A.P. handles 15 amps and is specifically designed for this job. The home depot version is not designed for HID lighting. It is designed for an attic fan. I think when it comes to safety being cheap is counter productive. A 600 watt light runs a little bit higher than 5 amps. So that thing would only work for 400 watt or lower. Now you might get lucky and a 600 watter might not trip it, but would you want to max out a safety product? You are only suppose to run 15 amps on a 20 amp breaker for safetys sake so why would maxing out this Home Depot 5 amp product be safe? Especially when it is not designed for this application. I personally would not do it. You are talking safety, and then trying to be cheap. Again those two things do not go together.

If you haven't already got your light timer(s), you may want to consider the Sentinel MDT-1..
"HI-Temp protection will disable HID Lights if the temperature exceeds the maximum level set by the user"

Thanks you guys for your replies!
@nordowell
Correct me if im wrong, but your setup is designed to turn ON at a certain temp. I need to turn OFF my lights at a certain high temp to prevent over heating
@Ozarks
That thing is awesome, but a little out of my price range.
@robert
The one u linked from Home Depot is perfect. but im worried about amperage like ozarks said.
The 150 watt Ballest i am using is rated (in Amps):
Operating: 3.2
Open Circuit: 0
Starting: 4.05
Recommended fuse: 15
As you can see everything is under the maximum 5 amps except the "recommended fuse". Do you guys foresee a problem?

your well under the rated amparage @ 4 for startup thats what will pop a fuse then it pulls 3 amps running will work fine.......INDUCTOR® In-Line Duct Fans. Also controls 110V lights, dampers, fans, etc.

I did find this one that handles 15 amps as well, but is cheaper.

I'm not familiar with thermostats for growing, but I have used proportional thermostats for reptile cages and there's some very cool ones out there.
If you don't want to mess about with the lighting you could tie a squirrel cage fan or some other hi volume fan into a thermostat and have it spin up when the temps get to high, circulating some of the room air in.
You can also get ones that will phone you when the temps go critical or there's a significant status change (very important when the thermostat is monitoring an incubator full of eggs.) Probably useful in this situation as well
Cheers.

try this for $35:

very versatile - it can be programmed for any temperature setting - to cool or heat. I just picked one up for my winter shed grow to keep the interior above a certain temp.
Great link; beats the shit outta the CAP for twice as much.
Just ordered one of these, I'll let you know how they do.
