Baymaster 250/400
High Bay Luminaires
For 150W, 250W or 400W HPS Lamps, 175W, 250W or 400W MH
Lamps, 250W or 400W MV Lamps, or 300W-500W incandescent
lamps.
Applications
• For illumination of manufacturing,
storage, and other indoor areas.
Features
• Standard Baymaster fixtures operate
in high ambient temperatures. All units
suitable for minimum 90°C supply wire.
• High efficiency (up to 78% with 250W
HPS lamps) with exceptionally long lamp
life—economical to own and operate.
• Pre-wired, integral ballasted, with
multi-tap primary for 120, 208, 240, or
277 volt lines or with 480 volt primary.
Ballasts are highest quality, Class H
insulated, U.L. listed C.W.A. types,
thermally isolated for cooler operation
and long life. Grounding wire provided.
• Ballast housing is finned, die-cast
copper-free aluminum, finished with
corrosion resistant powder-coat white
polyester.
• Sockets are heavy duty porcelain
mogul base, with spring loaded, nickel
plated center contact and heavy gauge,
nickel plated brass screw shell with
double lamp grips to prevent lamps
from loosening due to vibration.
• Efficient, low glare, compact reflector is exceptionally rugged, heavy gauge
Alzak® finished aluminum.
• Reflector installs and adjusts to wide,
medium, or narrow distribution (without tools) by repositioning stainless
steel spring locks.
• Installation is quick and easy: (1)
mount junction box to 3/4" conduit, (2)
slide ballast onto junction box, (3) make
connections, (4) install lamp, (5) snap
reflector in place.
• Open-top reflector design keeps reflector clean because of thermal barrier and chimney effect, and provides
up-light to relieve contrast.
Options
• All units available with a sensor circuit for automatically lighting an auxiliary safety lamp if a power dip or lamp
failure extinguishes the HID lamp.
Compliances
• Ul. Listed, UL Standard 1572,
Damp locations.
