What is the cost on these?

Really focused, resulting in the high par values.

The little sub note on the image in the first post says based off replacing a 250w mh with 4 of the Ecoray 60's
So 4 60's = 250w mh.
And their power savings are based off $0.25/kWh, A little more then 2.5 times what the rate in Edmonton is.
I bet replacing with 120 degree lens would not give you anywhere near the par values, they are only 1w LED's. Not to mention finding a 120 degree lens for that led might be very hard or impossible.
