New Fluorescent Tube Efficacy Standards: Be Efficient

Last week, EISA Act 2007: Be Efficient, discussed the Energy Independence and Security Act of 2007, and its affect on the manufacture of general service incandescent lamps.

This week, the impact of the Department of Energy Standards will have on the manufacture of inefficient general-service fluorescent lamps (GSFLs) beginning July 14, 2012.

On July 14, 2009, the Department of Energy published a final rule amending the energy efficiency standards for GSFLs. This rule restricts the manufacture of lamps that do not produce more than the minimum number of lumens per watts. This means that most T12s will no longer be manufactured, as they do not meet the efficiency standards. The purchase and sale of these lamps will not be illegal, however the manufacture of them will be. The new standards are:

 

Lamp/Tube   Type

Correlated   Color Temperature (CCT)

Minimum   average lamp efficacy (lm/W)

4-foot   medium bipin

≤4,500K

89

>4,500K   and ≤7,000K

88

2-foot   U-shaped

≤4,500K

84

>4,500K   and ≤7,000K

81

8-foot   slimline

≤4,500K

97

>4,500K   and ≤7,000K

93

8-foot high   output

≤4,500K

92

>4,500K   and ≤7,000K

88

4-foot   miniature bipin standard output

≤4,500K

86

>4,500K   and ≤7,000K

81

4-foot   miniature bipin high output

≤4,500K

76

>4,500K   and ≤7,000K

72

 

The following fluorescent lamps do not meet standards:

  • T32T8 4’ 700 series lamps will be phased out.
  • Majority of today’s F40 and F34T12 lamps and all FB40 and FB34T12 U-lamps
  • All of today’s 75W F96T12 lamps
  • All of today’s 60W F96T12/ES fail except for a few 700/SP & 800/SPX
  • All of today’s 110W F96T12 HO lamps
  • All of today’s 95W F96T12/ES/HO

Exceptions

  • Lamps with CRI ≥ 87
  • F96T12/CW/HO/CT & D/HO/CT

There are a variety of options to replace outdated T12’s including retrofit kits and replacing the fixture. Many of the new retrofit kits on the market can convert T12 fixtures to a new energy efficient alternative very cost effectively. The most common type of retrofit kits convert T12’s to T8’s. The range of benefits from using retrofit kits are not only limited to energy savings from the conversion, but also additional energy savings can be achieved from delamping, and retrofit kits are available in multiple styles that can update the look of a fixture as well.  An example of delamping is using a retrofit kit to convert a four lamp T12 2X4 lay-in to either a three or two lamp F32T8 2X4 lay-in with a reflector. The reflector aids in providing the additional lumen output needed to match the original lumen output of the T12 fixture using fewer lamps. Completely changing out the fixture is also another option that may be more beneficial in the long term. New fixture choices include T8, T5, LED, induction, plasma, solar power, and more. Depending on the application, using a new fixture may be the best course of action to comply with new standards and achieve the goals of the project. Either option will conform to the new standards set forth by the Department of Energy, and reduce long-term energy and maintenance cost.

These standards are set to increase the energy efficiency of US business and consumers by reducing their energy consumption. Have you done your part?
