Biax S Lamps Low wattage lamps were the first GE Biax introductions, and are
available with either two or four pin caps. Argon is the tube filling gas. See Figure 6.3.
Figure 6.3.
The two pin versions have an
internal starter built into the cap and are not dimmable. The four pin versions require external
starting and are suitable for dimming and emergency lighting. Both versions require a separate
ballast as for a conventional fluorescent lamp. Biax S lamps have a rated average life of 10,000
hours based upon 3 hours per start. All compact fluorescent lamps feature Polylux phosphors so have
excellent colour rendering (Ra 82). The colours range from 2700K to 4000K.
Primary applications for Biax S
(and Biax D, Biax T, Biax Q, and 2D) are to replace less efficient incandescent lamps in:
-
downlights
-
entrance and security
lighting
-
task lighting
-
wall washing.
Primary applications for Biax L
lamps are to replace linear fluorescent tube and low wattage HID lamps in:
-
uplights
-
recessed louvered ceiling
luminaires
-
accent lighting.
Four primary advantages of Biax S
lamps:
-
Energy saving: much higher efficacy
than incandescent lamps.
-
Long life.
-
Choice of colour
temperature.
-
Design flexibility: more light with
less unwanted heat.
Biax L Lamps
All are four pin and are dimmable.
They use remote control gear which
can be either a conventional ballast and starter or the high frequency electronic type. High
frequency ballasts must be used with the 40W and 55W lamps Rated lamp life is 10,000 hours based
upon 3 hours per start.
