erm! well to run as in the amount of power there much more efficient than HPS.. however HPS kick out a lot more light for your space which at the end of the day is what you want.

Enviros Kick out less heat which is something to think about 2. There also pretty poor to flower with. ul get a lot more bud with a 250 hps than a 200 enviro light.

There best used for propagation and veg and for that they do the job well and efficiently
