Spot-On hunting lights was created by Kevin DeVuyst, out of the need for better built, high performance scanning and weapon mounted hunting lights. Spot-On is a custom shop. Each light is hand built on carefully chosen hosts. Each light is fully disassembled and inspected for defects. Tail cap ground issues, lens focusing problems are some of the issues addressed with each build. Only the highest bin, highest quality emitters from USA sources are used, not counterfeit emitters commonly found in cheap chinese lights. Solid copper MCPCB's are used in most of the lights. The circuit boards used in Spot-On lights are high quality circuits carefully matched to the emitter being used. Each light gets tested on a digital lux meter to verify light output. Every light gets a two hour burn-in before it leaves the shop.
Spot-On also does repairs and modifications on most LED flashlights.
