B232I120HE 
"The new Triad® High Efficiency Lamp/Ballast System from Universal Lighting
Technologies is the most significant advancement in linear fluorescent
energy savings in more than a quarter century. The new system delivers a
40% energy savings compared to conventional magnetic T12 energysaving
systems and 11% versus standard electronic T8 systems."

B259I120HPL  Specific model for the 8 foot light
mentioned by the LA place. Plus it's the only F96T8 .78 ballast factor that
I could find.

Advance Online Catalog  The ballast that begin with ROP are Optanium
(high efficiency) line

GE232MaxN/Ultra 
"Systems combining UltraMax electronic ballasts and T8/WM lamps can deliver
up to 40% energy savings over standard electromagnetically ballasted T12
systems."

WHY SHOULD THE CUSTOMER HAVE TO PAY TWICE?

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:

Bulbs (yellow is recommended by LA people but 4100

F96T8/TL850/PLUS ALTO  5000 K is 5780/5375 lumens, this appears
to be the only 8 foot T8 line that Phillips has.

Old T12s (note that even the new standard T12s
only have a color rating index of 70 compared to 86 for the T8s. The LA
people
claim you
can go with a ballast factor of .78 (.88 is normal) and the increased color
rating will make it appear that it has the same light as the old T12s. See
the light above the mailbox that shows this effect somewhat in that in has a
higher Kevin but the same color rating as the rest. This is probably even
for true for the
Advantage T8s in that they have more lumens per watt than the standard
T8s. The Advantage is not available for the 8 footers.

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
ROP2P59SC (.86 ballast factor) for the 8
footers and the
ROP2P32LWSC (.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
