What is cob (chip on board) technology? what makes it different?

Chip On Board Technology is a newer technology of LED packaging for LED light engines. Multi LED chips are packaged together as one lighting module. When it light up, it looks like a lighting panel. The difference is COB technology only requires one or 2 circuits for the whole chip so you can fit many LED’s on the board, whereas old SMD’s and T LED’s must use 1 circuit per LED so you can only fit a few LED’s on a board. We can fit 100 LED’s where we could only fit 10 before. Having more LED’s on 1 board makes a brighter more efficient light. CAT Lights MANUFACTURER answered on July 20, 2017

Is the body made of plastic ?

ABS body Acrylonitrile butadiene styrene (ABS) (chemical formula (C8H8)x·(C4H6)y·(C3H3N)z) is a common thermoplastic polymer. Its glass transition temperature is approximately 105 °C (221 °F).2 ABS is amorphous and therefore has no true melting point.ABS is a terpolymer made by polymerizing styrene and acrylonitrile in the presence of polybutadiene. The proportions can vary from 15 to 35% acrylonitrile, 5 to 30% butadiene and 40 to 60% styrene. The result is a long chain of polybutadiene criss-crossed with shorter chains of poly(styrene-co-acrylonitrile). The nitrile groups from neighboring chains, being polar, attract each other and bind the chains together, making ABS stronger than pure polystyrene. The styrene gives the plastic a shiny, impervious surface. The polybutadiene, a rubbery substance, provides toughness even at low temperatures. For the majority of applications, ABS can be used between −20 and 80 °C (−4 and 176 °F) as its mechanical properties vary with temperature.3 The properties are created by rubber toughening, where fine particles of elastomer are distributed throughout the rigid matrix.FANCY TERM FOR PLASTIC OF SOME SORT

What is the color temperature of the light? Is this a cold, warm, or neutral white light? A Kelvin rating would be nice...

Good day. The color temperature is a white light (LED). The Kelvin rating is 6300 - 7000. If you have any further questions, please contact us at info@catlights.com. Thank you.
