Ran my total station off a 1200 lumen work light instead of my old halogen setup, and the sighting errors dropped off a cliff
I do layout on a mid rise in Fort Worth and for two years I kept fighting reflections on my prism in the afternoon. Last month I swapped the old halogen work light near my setup for a 1200 lumen LED light and started shooting within 15 minutes instead of an hour. The first week my closures went from about a quarter inch off to under a tenth, and I stopped second guessing my backsights. Has anyone else found that light color throws off their readings, or is it just me?

1200 lumens on an LED is a totally different animal than halogen, that color temp sits way cooler and the prism catches it clean. Halogen throws all that yellow orange light and your glass is picking up every bit of that bounce, which is why your afternoon shots were trash for two years. We run白光 LEDs on our setups in Dallas and saw the same thing, closures tightened up inside a tenth pretty fast. Cool white also puts out way less heat so your instrument doesn't drift as much when you're set up close to the light. I would not go back to the old lights even if they paid me.
