The following is for the 8 footers.  No one that I could find makes a high efficiency ballast with a .78 ballast factor.  The LA people recommended the Universal, which is not a high efficiency ballast but there is only 6 watts difference between that and the Advance high efficiency .86 (normal) ballast factor:

Calculated savings with .78 ballast:

On 8 foot lights:  160 - 100 = 60 watts x 24 hrs x 30 days x 5 lights on 24 hours per day = 216000 watt hours = 216 kwh x .14/kwh = $30.24 savings per month.

On 4 foot lights: 96 - 48 = 48 watts x 24 hrs x 30 days x 3 lights (counting elevator) on 24 hours per days = 103680 watt hours = 103.68 kwh x .14 = $14.52

$30.24 x $14.52 = $44.76 savings per month

Calculated savings with .88 ballast:

On 8 foot lights:  160 - 110 = 50 watts x 24 hrs x 30 days x 5 lights on 24 hours per day = 180000 watt hours = 180 kwh x .14/kwh = $25.20 savings per month.

On 4 foot lights: 96 - 55 = 41 watts x 24 hrs x 30 days x 3 lights (counting elevator) on 24 hours per days = 88560 watt hours = 88.56 kwh x .14 = $8.27

$25.20 + $12.40 = $37.60 savings per month

Note:  Savings would be higher if we are going over our baseline allowance and I think we probably are.

Calculated savings with ROP-2P59-SC (.86 ballast factor) for the 8 footers and the ROP-2P32-LW-SC (.78 ballast factor) for the 4 footers.  This is the Advance Optanium line sold.  The Advance brand is sold at Home Depot but we would have to special order the Optanium model.

On 8 foot lights:  160 - 106 = 54 watts x 24 hrs x 30 days x 5 lights on 24 hours per day = 194400 watt hours = 194.4 kwh x .14/kwh = $27.22 savings per month.

On 4 foot lights: 96 - 48 = 48 watts x 24 hrs x 30 days x 3 lights (counting elevator) on 24 hours per days = 103680 watt hours = 103.68 kwh x .14 = $14.52

$27.22 + $14.52 = $41.74 savings per month
