MAGNETIC DISTORTION ELIMINATED! New "Royalton" BALANCE ILLUMINATOR Removes Source of M a g n e t i c D i s t o r t i o n , Vibration, and Hum Operates 35% cooler BALLAST IS 6 FEET AWAY FROM THE BALANCE Only the "Royalton" Balance Illuminator is so made that the ballast is 6 feet away from the balance . . . (In other lights the ballast is within the housing, thus emitting a strong magnetic field in the immediate area of the balance. The ballast also vibrates, hums, and develops considerable heat) . . . A l l this is overcome In the "Royalton" by the proper functional placing of the ballast.
COOL WHITE LIGHT WITHOUT GLARE - No Vibration!
Cooler operation due to gravity convection.
Gravity Convection Reduces Heat Because of the location of the ballast, the "Royalton" operates at the minimum temperature of the fluorescent lamp itself. A_ complete system for gravity convection further reduces.the temperature. A i r is circulated, heat withdrawn constantly through air intake and exhaust ports the full length of the reflector and lamp housing. SPECIALLY COATED REFLECTOR in the "Royalton" Intensifies the light reflected into the balance while accelerating the convection of heat up and out of the housing.
AN electrical components are Underwriters' Approved . . . For operation on M5V 60 cycles AC only . . . Complete with 14 watt GE lamp, cord, plug and switch; ready to plug in.
Less "Royalton" Balance Lights are finished in handsome grey wrinkle and fit all conventional type analytical balances, both wood and metal cabinets.
