The Kosnic 9W LED 2-Pin GR8 Lamp emits 900 lumens of 4000K cool white light in a 120° beam. It has a peak luminous intensity of 270 candelas and a mighty luminous efficacy of 100 lm/W. A minimum CRI 70 score signifies good-quality colour rendering.

Further advantages of the Kosnic LED lamp over fluorescent equivalents include: instant full-power, negligible UV or IR output, zero mercury content, reliable low-temperature performance (down to -20°C), shock-proof and vibration-proof.

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