Replacement Compatibility

Compatible with multi-application fixtures including yard lights, street fixtures, landscape lighting, security lights, parking areas and residential street lights that originally used the DONSBULBS H39KC-175/DX or H39KB-175 mercury vapor bulbs. The LED technology eliminates frequent maintenance cycles associated with older HID lamps while maintaining the same physical footprint for hassle free changes. Property owners appreciate the reduced operating costs and improved light quality that comes from switching to solid state illumination in legacy systems. Installation takes only minutes by simply unscrewing the old bulb and inserting this new unit into the existing socket. No additional drivers or ballasts are necessary because the integrated electronics handle voltage regulation internally.

Additional considerations include stable thermal management that prevents overheating during extended operation periods in varying climate conditions.
