Osram ST8A-EM 18.4 W/840 1200 mm EM

Product benefits

• Quick, simple and safe replacement without rewiring
• Energy savings of up to 60 % (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
• Extremely break resistant thanks to aluminum heat sink and polycarbonate cover

Areas of application

• General illumination within ambient temperatures from –20…+50 °C
• Illumination of production areas
• Traffic zones and corridors
• Supermarkets and department stores
• Industry

Product features

• LED alternative to classic T8 fluorescent lamps in CCG luminaires
• Bright, robust and durable
• Uniform illumination
• Wide beam angle: 160° (0.6 m), 150° (1.2 m, 1.5 m)
• Mercury-free and RoHS compliant
• Type of protection: IP20
• Integrated ECG with high power factor
• Equipment / Accessories
• Suitable for operation with low-loss and conventional control gears

Safety advice

• 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.
