Other advantages of the Kosnic 18W LED 4 Pin GR10Q 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.

The Kosnic 18W LED 4 Pin GR10Q Lamp emits 1500 lumens of 4000K cool white light in a 120° beam. It is equal in output to a 38W fluorescent low-energy DD bulb, and has a 130 lux measurement at 2 metres. Luminous intensity is 520 candelas.

When installing this lamp into a regular 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 long lifespan of the Kosnic 18W LED 4 Pin GR10Q Lamp will reduce running and maintenance costs considerably, and bring a return to any investment.
