C.O.B. (Chip On Board) LED GU10 – 36º Beam Angle

This 5W C.O.B. LED GU10 lamp in cool white is suitable for use in all 240v lighting inside and outside the home. The most common applications for an LED GU10 bulb is in a spotlight or spikelight in the garden. COB LED GU10s are very reliable with a long life expectancy, have a high lumen output and also use less energy being of a lower wattage. Most of lighting has plenty of space for slightly larger GU10s, resulting in more airflow to the bulbs and keeping them cooler when running. Please note: These COB GU10s are approximately 10mm longer than standard halogen GU10s, therefore please remember to check that there is plenty of space in your fitting.

  • Voltage: 240v
  • Wattage: 5W (Genesis LEDs)
  • Lumen Output: 410-  470 Lumens

What Is COB Technology?

COB (Chip on Board) is an assembly technology of the semiconductor in which the bare microchip components, known as “die”, are mounted directly on the substrate or printed circuit board without packaging. Once connected, they are covered with epoxy or plastic for protection and insulation. A number of LED chips are usually mounted together creating one compact lighting panel. The main advantages of COB technology are that it allows more heat to escape, thus keeping the lamp much cooler than many other equivalents,and reduces unwanted glare.

Colour Temperature

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.
