How the Maxibright Compact 400w Ballast Works:

The Maxibright Compact 400 Watt Ballast converts mains electricity to the correct voltage and current to start-up and power a 400 Watt HPS or MH lamp by using a traditional magnetic core & coil system.

How to Use the Maxibright Compact 400w Ballast:

The Maxibright Compact 400 Watt Ballast runs warm in use and should be located on a flat, firm, surface (not carpet) in a well ventilated place. The Maxibright Compact 400 Watt Ballast should never be covered and there should be no combustible items in the vicinity. Connect the input lead of your reflector to the output lead of the ballast ensuring the cable is not pulled tight and does not come into contact with anything hot (e.g. lamp, reflector, ballast). Ensure your lamp is tightly screwed into the bulb-holder and that your reflector is at the correct height.

The wattage of your ballast MUST match the wattage of the lamp you are using or there will be a high risk of fires or equipment damage. Always consider the inrush current drawn by a ballast when it is switched on. Your mains supply may trip out if several come on at the same time. Connect the mains plug into an electrical outlet socket and switch on. The ballast will start-up and light the lamp. Please note that in the event of an interruption to the mains supply, the ballast may not be able to restart the lamp until it has cooled back down.

Economical and well made, this ballast is perfect for beginners or even to keep as a spare, just in case!

For use with 400 Watt HPS or MH lamps only.
