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***

A true turtleneck that retains a snug high neck.
Color: White, Size: X-Large
I've found this brand to have gotten better over the years as far as offering the American market what it needs in terms of realistic sizing. I only wish they'd realize that there are a lot of us who are long in the back and arms where my only choice is to go a size up and sacrifice a slim fit for sleeves that are long enough plus a back that doesn't go up past my waist just because I reach up for something, that and I like to be warm. So these are such nice quality turtlenecks that it's hard to complain about but maybe the company will read this. The snug neck stays up is plus number one since that's why I'm buying a full neck. They come with very nice weaves in the fabric, good enough for casual or formal wear. Finally the warmth you seek is there but I've worn them in what most would think isn't the right temp for a turtleneck. Also they have them in white! Yes, a lot of others just don't for reasons I can't fathom, and the pic you're seeing is accurate, these will form to your shape without being ridiculously thin material. Several washes later and they are as fine a garment as when I first wore them. I've only found one other brand that compares to these but it's much more expensive, COOFANDY is affordable in these times of expensive everything. Warm but also a lightweight shirt, I've gotten them really dirty with actual dirt and it washes out so well you'd never know it. Don't let my taking off one star stop you, try one yourself and you'll be coming back for more.
