ST8U-EM 20 W/4000K 600 mm

Product benefits
  • Quick, simple and safe replacement without rewiring
  • 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
