Certified with an A+ energy rating, the Kosnic 12W LED 4 Pin DD Bulb emits 1200 lumens of 2700K warm white light in a 120° flood beam. This equates to an excellent luminous efficacy of 100 lumens per watt and a peak luminous intensity of 350 candelas.

Other advantages of the Kosnic 12W LED 4 Pin DD Bulb over fluorescent equivalents include instant full-power start, high tolerance of frequent switching, negligible UV or IR output (less likely to attract insects or cause fading), no mercury content, reliable low-temperature performance (down to -20°C), shock-proof and vibration-proof.

To achieve maximum energy savings with the Kosnic 12W LED 4 Pin DD Bulb, the control gear of the fitting should be bypassed during installation for direct supply from the mains. This retrofit bulb is non-dimmable.
