Osram ST8RB-EM 20 W/840 1200 mm Rotatable EM

Product benefits

• Quick, simple and safe replacement without rewiring
• Low maintenance costs thanks to long lifetime
• Energy savings of up to 65 % (compared to T8 fluorescent lamp on CCG)
• Instant-on light, therefore ideally suitable in combination with sensor technology
• Very high resistance to switching loads
• Also suitable for operation at low temperatures

Areas of application

• General illumination within ambient temperatures from –20…+45 °C
• Cooling and storage rooms
• Corridors, stairways, parking garages
• Ideal for simple lighting tasks

Product features

• LED alternative to classic T8 fluorescent lamps in CCG luminaires
• Uniform illumination
• Wide beam angle: 160° (1.2 m), 150° (1.5 m)
• Integrated ECG with high power factor
• Mercury-free and RoHS compliant
• Type of protection: IP20

Equipment / Accessories
Suitable for operation with low-loss and conventional control gears

Safety advice
Operation in outdoor applications in suitable damp-proof luminaires possible according to data sheet and installation instruction.
Not suitable for operation with electronic control gear.

Legal advice
When used to replace a T8 fluorescent lamp the total energy efficiency and light distribution depends on the design of the lighting system.
