Description
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***

How to use
A 400V lamp will not run on an ordinary 240V ballast. Check your ballast is a 400V model before you buy. Once fitted, it dims in the same way as a 240V lamp.
Keep the box: the 12-month warranty depends on the original packaging. Standard 240V lamps are in HID lighting.
