I have both the single and double row bars on my truck.
Single row is a Vision X knock off that performs amazingly well and you can get the info here

I offer 20", 30", and a 40" bar with 10 watt CREE LED's.
Super bright bar for the money and very nice quality but it's made in China which some people don't like.
I also have the KC Hilites 30" C-Series LED bar that performs very well and is reasonably priced backed by a 23 year warranty.
They've been around since 1970 so they know what they're doing.
I'm also a dealer for Rigid and Vision X if your interested in those.
Send me a pm if you'd like a price on one.
