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.

Funny how that works with lots of stuff, not just trails. The song you skip on the album ends up being the one you play on repeat a year later. The neighbor you avoided for months turns out to be your best friend on the block. Stuff we dread usually has some unknown to it, and unknown feels like work. Then you actually do the thing and the fear was just a guess.
