Color Temperature (Kelvin)
Color temperature, measured in kelvin (K), describes the tint of white light: around 3000 K is warm (yellowish), 5000–5700 K is neutral daylight white, 6000–6500 K is cool white. Most machinery LED work lights ship at 5700–6500 K.
Halogen lamps sit near 3200 K; LED work lights typically run 5700–6500 K. Cooler white improves contrast and reduces operator fatigue during long night shifts, which is why daylight-white is the machinery standard.
When warmer light wins
In fog, dust or snowfall, very cool light scatters back into the operator’s eyes. Amber auxiliary lamps or lower-K options cut through airborne particles better — one reason fog lamps stay selective about colour temperature.
What to specify
For general work lighting, 5700–6500 K with high effective lumens is the default. Note that colour temperature says nothing about brightness — see raw vs effective lumens for the output side of the specification.

Raw lumens state the theoretical output of the LED chips; effective lumens state the light that actually leaves the lamp after optical, thermal and electrical losses. Effective lumens are the honest number to compare.
Beam Patterns (Flood, Spot, Combo, Trapezoid)A beam pattern describes how a lamp distributes its light: flood beams deliver wide, short-range illumination; spot beams project a narrow, concentrated beam over distance; combination beam lights provide both from a single housing.
