400V Lamps


400V Grow Lamps are the next generation of HID lights and output around 10% more usable light than standard 240V grow lamps, that are currently in use.

They require a different ballast to power them - we currently sell the Maxibright Promax Gold 600W/400V ballast with other models expected to follow in the coming months.

You can dim these lamps in the same way as you would a normal 240V lamp, the main difference is just the enhanced PAR output. They cost a bit more than 240V lamps at the moment, as they become the norm in the grow lighting industry expect the prices to drop to about the same level.

***Please retain original packaging for your lamps to validate the 12 month warranty***
