CFL Non-Integrated 2D WattMiser Lamps from GE Lighting Europe

2D Watt-Miser for energy saving

In response to the demand from the market for a lower energy consumption GE has developed the extra energy saving 2D™ Watt-Miser™. GE Watt-Miser™ is a new generation of lamp family where end users can save additional energy versus regular compact fluorescent lamps on the market. Currently this unique GE 2D™ range has this extra feature where extra energy saving can reach up to 12%.


Biax™ 2D™ compact fluorescent lamps have been available for many years but GE is introducing the next generation of lamps under the name of 2D™ Watt-Miser™. These are available in 16, 21, 28 and 38 Watt in a wide choice of colour temperatures, these lamps are a direct replacement to existing 2D fixtures delivering the same life of 15,000 hours in case of 28 and 38 Watt but additional energy saving performance, 2D™ Watt-Miser™ lamps give similar lumenas the lamps they are replacing but up to 12% energy saving dependent upon ballast and wattage.

In response to the demand from the market for a higher light output version of the 2D™ lamp, GE offers the 55W using the T5 28W/38W envelope size. The high luminous efficacy has been retained in the 55W by incorporating an amalgam which overcomes the fall in efficacy that occurs with increased lamp loading. The 55W lamp has a cap with dedicated key. The cap material withstands the higher temperatures generated by the increased lamp power while the modified holder key for the 55W 2D™ will prevent accidental insertion of any lower rated 2D™ lamp into a 55W socket.

The T5 size (14% smaller overall diameter) will allow luminaire manufacturers to design new fittings with improved optical control in addition to the well-known uniformity of light of the Biax™ 2D™ concept.


Lamp technology

In response to the demand from the market for a lower energy consumption GE has invented the extra energy saving 2D™ Watt-Miser™. These lamps are designed to retrofit, into existing fixtures, provide similar lamps performance but save energy at the same time.

New 2D™ Watt-Miser™ lamps are energy saving compact fluorescent tubes formed into a "2D" shape. All types are available with a 4pin cap which permits use with conventional or electronic (high frequency) control gear, dimming and emergency lighting circuits.

The 16-28W types are also available with 2pin cap which contains a starter switch and an EMC (RIS) capacitor.


The flat profile makes the 2D™ Watt-Miser™ an ideal choice for building into slim, attractive luminaries. Its two dimensional shape is suitable for both up lighting and downlighting applications, where directional lighting is required. Due to its shallow, broad configuration, it spreads light over a large area without the need for expensive optics.
