Xcel labels them:
Type A: 70 watt HPS equivalent, 3500 delivered lumens
Type B: 100 watt HPS equivalent 4000 delivered lumens
Type C 150 watt HPS equivalent 6000 delivered lumens
Type D: 250 watt HPS equivalent 14000 delivered lumens
Type E: 400 watt HPS equivalent. 25000 delivered lumens.

As I posted before, Mn/DOT lables their LEDs at the recommended mounting height:
40= 40 foot mounting height, 250 watt HPS equivalent
49= 49 foot pole mounting height, 400 watt HPS equivalent.

I took out my light meter and measured 2.02 foot/candles underneath one of these fixtures (compared to 1.7 for a fixture with a new sodium lamp, and 1.3 with an aged sodium lamp. Obviously they're a bit brighter to allow for lumen depreciation before they need to be replaced. When used with improper spacing as is pretty common, the space in-between is definately darker, .01 footcandles, or essentially nothing, compared to .07 footcandles with semi-cutoff sodium lights.

Well... they have started installing these in 3000k. The color is too pink and the optics are still awful IMO but at least they aren't as bad as the 4000k and 5000k units.

Any machine is a smoke machine if you operate it wrong enough.
