Product information
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 lumen
as the lamps they are replacing but up to 12% energy saving
dependent upon ballast and wattage. Saving energy cost:
16W lamp runs on 14W*, 21W lamp runs on 19W*, 28W lamp
runs on 24W* and 38W runs on 34W*.
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.
DATA SHEET
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.
