How do you measure light levels
WebJan 7, 2024 · The average LED light temperatures range from 2700K (warmest) to 6000K (coolest). While a 2700K bulb will cast a cozy, orange glow and a 6000K bulb will emit a crisp, blue light, the brightness will nearly be the same. Changing from 4000K to 5000K will typically only increase brightness by 20-60lm, in the same fixture, of course. WebApr 14, 2024 · The higher the IP level, the better the waterproof and dust resistance. IP levels range from 64 to 69K. Bars with IP between 64 and 67 are completely protected from dust and water sprays or jets but not from flooding. Quality LED light bars have IPs of at least 67 and can withstand soaking up to 1m.
