LED light bar 240W, combo of 90° and 8°, 6000K, IP68, 12-24V
Led headlight panel for car as work light, not high beam. This additional light has 90° LEDs in the centre and 8° LEDs on the edges, so there is no side glare. Consists of 80pcs 3W high quality Cree LEDs. The light has a colour hue of 6000K and a wattage of 240W. Lumen output 20 600 (raw lumens). IP68. Please take into account the type of vehicle and the way the light is used.
Led light ramp for an efficient work light for your car or boat. It is also a very effective light for facades and, thanks to the LED wedge, creates a clear light pattern on the wall.
This luminaire has 90° LEDs in the centre and 8° LEDs on the edges, eliminating side glare. The ramp is made up of 3W high quality CREE LEDs. This light bulb has a light colour tone of 6000K, which is very natural outside and has a wattage of 240W (lumen output 20 600 raw lumens). The light comes on quickly and is energy efficient for its wattage.
This LED luminaire is made of cast aluminium (body) and the lens is PC plastic. The fixtures are also aluminium and are included in the package.
The operating voltage is 10-30V DC, which means that it is suitable for both 12V and 24V systems (cars, boats, solar powered cottages).
High level of waterproofing, IP68.

WHAT IS CRI, THE COLOUR RENDERING INDEX
High quality LED lights also have a high colour rendering index, or CRI. A good colour rendering index (CRI) for home use is above 90, and nowadays many market lights are unfortunately closer to 80.
CRI tells you how well an LED light displays colours as they should be. For designers and architects, as well as interior designers, it should be one of the most important considerations. Make sure the lighting is perfect so that your artwork is what it is meant to be.
Colour rendering index
The colour rendering index is expressed as a number on a scale from zero to 100, where 0 = no colour rendering and 100 = full colour rendering. The colour rendering index of LED lights is also known as Ra, which is measured on a smaller scale than CRI. This Ra value does not include red tones or skin tones, for example, so it is a 'glossed' figure for the true quality of an LED light.
RA value
The Ra value measures the reproduction of colours using eight different reference colours. CRI takes into account the wider (15) wavelength range, including reds and other warm colours.
The Ra value is calculated by cutting the wavelength range, weighting the blue and violet tones, and calculating the weighted average of R numbers 1-8.
Excluded from the Ra value are, for example, the colour rendering of bright reds, yellows and greens, and shades close to skin tone. These are described by R-values between 9 and 15. The following is a picture of a measurement result that easily confuses the consumer.
This measurement is from a 9W CCT Led spot
