The Kosnic 12W LED 4 Pin GR10Q Lamp emits 940 lumens of 4000K cool white light in a 120° beam. It is equal in output to a 28W fluorescent low-energy DD bulb and has a peak luminous intensity of 320 candelas.

Other advantages of the Kosnic 12W LED 4-Pin Lamp over fluorescent equivalents include: instant full-power start, negligible UV or IR output (less likely to attract insects or cause fading), zero mercury content, reliable low-temperature performance (down to -20°C), shock-proof and vibration-proof.

When installing this Kosnic lamp into a standard fluorescent fitting with a magnetic ballast, the starter should be removed beforehand. With a high-frequency electronic fitting, the ballast needs to be completely bypassed.

The energy-efficiency and sheer longevity of the Kosnic 12W LED 4-Pin GR10Q Lamp will reduce running and maintenance costs considerably.
