• Why instant start
• 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 energy-saving 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
• GE-232-Max-N/Ultra - "Systems combining UltraMax electronic ballasts and T8/WM lamps can deliver up to 40% energy savings over standard electromagnetically ballasted T12 systems."

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:

* Same part number, different spec sheets.

Bulbs (yellow is recommended by LA people but 4100 K):

• 4 Foot, 32 Watt
  • F32T8/ADV850/ALTO - 5000 K is 3100/2950 lumens (most lumens per watt)
  • F32T8/TL850/ALTO - 5000 K is 2900/2800 lumens
  • F32T8/TL850PLUS/ALTO - 5000 K is 2950/2800 lumens
  • F32T8/TL950 - 5000 K is 2000/1860 lumens, very high color rating (CRI=98) for bathrooms
  • F32T8/ADV830/EW/ALTO - 4100 K is 2900/2750 lumens, 30 watt energy savers
• 8 Foot, 59 Watt
  • 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 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
