2009 Department of Energy Lumens Per Watt (LPW) Regulations for Linear Fluorescent and Halogen PAR Lamps

The DOE recently announced new efficiency standards for linear and U-shape fluorescent lamps, and halogen PAR lamps.

The new standards will become effective in the summer of 2012, and will eliminate nearly all 4-foot T12 lamps, some 4-foot T8 lamps, most 8-foot T12 lamps, and nearly all standard halogen PAR38, PAR30 and PAR20 lamps from the market.


Regulations for T5, T8, T12 and U-Shaped Linear Fluorescent Lamps

Effective July 14, 2012, linear T12, T8 and T5, and U-bend lamps must meet 2009 DOE regulations. 2-foot U-shaped, 4-foot and 8-foot lamps must meet minimum initial lumens per watt (LPW) requirements. Lamps above 4500K have a slightly lower standard. 


Refer to the table below for a breakdown of the lamps that will be affected by the regulations.

Fluorescent
Lamps
Wattage Color
Temperature
Lumens per
Watt (LPW)
Requirement
Impact
4 ft. T12 and T8
Linear

(Medium Bipin)
25W and
above
Up to 4500K 89 LPW All Standard 4 ft. T12 lamps are eliminated. F32 minimum 2850 lumens: Standard SP lamps at 2800 lumens don't meet standard. Current F32/SPX, High Lumen, F30, F28 and 25W meet standard.
4500K – 7000K 88 LPW
8 ft. T12 and T8
Slimline Linear
52W and
above
Up to 4500K 97 LPW Generally, 8 ft. T8 lamps meet standard. Most T12 lamps eliminated except 60W SPX/WM T12.
4500K – 7000K 93 LPW

8 ft. T12 and T8
High Output (HO)
Linear

(Cold temperature
lamps exempt)

All Up to 4500K 92 LPW Many 8 ft. T12 HO eliminated (both 110W nominal and 95W nominal) 8ft. T8 HO lamps meet standard. Cold temperature lamps are exempt.
4500K – 7000K 88 LPW
2 ft. U-shaped T12
and T8

(Includes 6", 3" and
1-5/8" spacing)
25W and
above
Up to 4500K 84 LPW All T12 2 ft. U-bend lamps are eliminated. T8 U-bend standard SP lamps are eliminated. Only a few T8 SPX U-bend lamps will meet standard.
4500K – 7000K 81 LPW
4 ft. T5 High
Efficiency
26W and
above
Up to 4500K 86 LPW All T5 HE lamps meet standard. (This regulation prevents manufacture of inexpensive T5 CW lamps.)
4500K – 7000K 81 LPW

4 ft. T5 High
Output

49W and
above
Up to 4500K 76 LPW All T5 HO lamps meet standard. (This regulation prevents manufacture of inexpensive T5 HO CW lamps.)
4500K – 7000K 72 LPW


Regulations for Halogen PAR38, PAR30 and PAR20 Lamps

Effective July 14, 2012, 40–205W halogen PAR lamps will be regulated by minimum LPW standards.

  • Standard halogen PAR lamps in all categories are eliminated in 2012
  • HIR PAR lamps are borderline; some current products pass, others fail narrowly
  • HIR PAR Plus lamps meet the standard. None of the existing PAR20 lamps meet the requirement
  • Redesign is required. All 130V lamps are likely to be eliminated.

For spectrally enhanced lamps, like GE Reveal®, LPW requirements are approximately 15% lower.


Examples of Fluorescent Lamps not covered (by minimum LPW standards):

Other length lamps not specifically mentioned (such as 2 ft., 3 ft., & 5 ft. lamps)

Lamps greater than 7000K

Lamps that are plant growth, cold temperature, colored, impact resistant (covRguard)®, reflector or aperture, reprographic, UV, & high CRI (≥ 87) lamps

Examples of Halogen Lamps not covered (by minimum LPW standards):

Lamps outside 40W–205W

Specialty lamps, including colored, rough/vibration service, shatter resistant and heat lamps
