Metal-halide bulb Philips 59664700, 228 W, 4200 K, 21 140 lm
The Philips 59664700 metal-halide bulb is a high-intensity discharge lamp designed for general, industrial and outdoor lighting applications. With a rated power of 228 W and a neutral-white colour temperature of 4200 K, it provides a clear, balanced light output of approximately 21,140 lumens. The lamp runs at a nominal current of 2300 mA and is supplied as a single unit for installation in compatible fixtures such as floodlights, high-bay luminaires and outdoor area light fittings.
This metal-halide bulb delivers high luminous efficacy and steady colour rendering suited to work and commercial environments. Its neutral-white 4200 K light helps maintain visual accuracy and reduces colour shift compared with lower-quality lamps. The 228 W power level and 21,140 lm luminous flux provide intense illumination for large spaces while offering a proven, long-standing technology for reliable performance in correctly matched gear and fixtures.
Install the lamp only in fixtures designed for metal-halide lamps with compatible ballast or ignitor rated for the indicated operating current. Ensure power is switched off and the fixture has cooled before replacing lamps. Position the bulb securely in the lamp holder and follow the fixture manufacturer’s instructions for wiring and mounting. Allow for a warm-up period after switching on; the lamp reaches full luminous output and stable colour within a few minutes.
Use only compatible control gear and follow local regulations for handling and disposal because the lamp contains mercury. For best performance, check fixture compatibility, provide adequate ventilation to manage heat, and replace lamps in groups for even light levels in multi-lamp installations.
