Regulations Included
- EISA 2007
- 2009 DOE Rulemaking on Incandescent Reflector Lamps
Requirements Per EISA 2007
Sets minimum LPW requirements for incandescent reflector lamps with a diameter over 2.25":
| Wattage Range | Minimum LPW |
| 40-50 | 10.5 |
| 51-66 | 11.0 |
| 67-85 | 12.5 |
| 86-115 | 14.0 |
| 116-155 | 14.5 |
| 156-205 | 15.0 |
Key Impacts from EISA 2007
Remember to compare photometric characteristics before making these substitutions:
-
Replace all wattages of K19 with halogen PAR16 or possibly PAR20
-
Replace 50W R20 with new 45W R20 or halogen PAR20
-
Replace BR40 between 65W and 205W with 65W BR40 or halogen PAR38
-
All white light BPAR/OPAR (one-piece) lamps have been eliminated
Requirements Per DOE 2009 Rulemaking
Sets new LPW minimums based on spectrum, lamp diameter, voltage and watts:
| Lamp Wattage | Spectrum | Diameter | Voltage | Minimum LPW (expressed as a formula based on the lamp watts)* |
| 40-205 | Standard | > 2.5” | ≥ 125 | 6.8 X (lamp watts)^0.27 |
| < 125 | 5.9 X (lamp watts)^0.27 |
| > 2.25” & £ 2.5” | ≥ 125 | 5.7 X (lamp watts)^0.27 |
| < 125 | 5.0 X (lamp watts)^0.27 |
| Modified | Requirements for modified spectrum lamps are approximately 17% less stringent then for lamps with a standard spectrum |
* = the '^' character in the formulae refer to exponentiation. E.g. the minimum LPW of a 72W lamp, with standard spectrum, a diameter over 2.5" and 130 voltage is 6.8 times the lamp watts raised to the 0.27 power. This equals 21.58 lumens per watt.
Key Impacts From DOE 2009 Rulemaking
-
All of today’s standard PAR halogen lamps will be eliminated
-
Most if not all 130V PAR halogen lamps will be eliminated
-
Compliant lamps, requiring more advanced coatings, will be more expensive RE first cost
