This 11W LED Kosnic bulb will not disappoint with its super bright lumen output of 1200 lumens, equivalent to that of an 83W incandescent lamp and saving up to 87% of energy. Being LED, the daylight white bulb reaches full brightness instantly making it ideal for use with PIR sensors where a bright light is required.

The colour temperature of a lamp is a measurement in degrees Kelvin (K) to determine the “warmth” or “coldness” of the light that it produces. Lamps with a low colour temperature produce what is described as a “warm white” light – often described as “yellow” or even “orange in very low colour temperatures such as old fashioned street lights. The higher the colour temperature, the cooler the light appears, eventually reaching what is known as a “daylight white” at approximately 6000K. Daylight White bulbs tend to have a blue tinge rather than yellow.
Lumens Output Vs. Wattage Equivalents
Lumens Output is the measurement of how bright a lamp actually appears once illuminated. Often when replacing light bulbs, an equivalent wattage is requested, however the Lumen Output can vary between different brands of bulbs with exactly the same wattage. The higher the lumens output, the brighter the bulb. Below is a simple chart to demonstarte what lumen output you would expect for certain wattages. Therefore, if replacing a 25W standard / halogen bulb with an equivalent LED, simply look for an LED lamp which has virtually the same lumen output (230-270 lumens) for the closest match. Equivalents are often estimated, therefore comparing the lumen output is the best and more accurate way to replace bulbs with low energy equivalents.
