Look here.
You likely know what is wrong.
Problem 1: Crazy Expensive!  
Problem 2: You pay big bucks for something less efficient!
Problem 3: You won't save money, You will actually be less efficient.
Just look at the LM/W: 400 Watt MH: 90. This LED: 89.
Combine that with glare, bad optics, and a few more things, you get a bad deal.

It actually looks good, But I would not like the halved brightness if they had MH before.

Quite sad that someone was foolish enough to buy this. You could get more lumens from a 320w PSMH lamp. I once saw a 20w LED wallpack rated to replace 400w PSMH.

What? 
It all boils down to marketing.

Its the Equivalence game. Assume that the reflector in the lantern have matte black finish, lamp is a Merc 5 times past its rated life, ballast is a resistor, and you really get the promised energy savings...

it's also supposed to be "accidentally" spraypainted black since it assumed that it is in an auto shop. Guess what? The fixture was rated for a lousy 520 lumens. Even a 20w CMH beats that by a ton.

What? If that's the 20 Watt LED, That's 26 LPW on a good day!
