content: After years of searching, I finally found a lamp from an operating room for my lab. This is fairly large one, the span with both arms out is about 12 feet.I want to do an LED conversion. Its currently halogen:"The AMSCO Centra 360 surgical light features a halogen light type with two light heads, 9,000 ft-c light intensity, 5 intensity adjustment steps, a color temperature of 4,400° Kelvin, and a depth of field of 29 inches"I'd like to keep the same lighting effect the lamp currently has, but that looks difficult as an LED package in the area where the lamps are is specific.My initial idea is to use a diffuser like an LED TV uses, but wrapped in a cone around the concave area. LEDs would be underneath the diffuser, potentially attached to the concave area directly.Anyone ever put one of these in their lab or done a similar conversion?

content: I used to have 5 of these in my old lab3 above the table, two behind the tableIN HOME LPU-02https://www.vseinstrumenti.ru/product/universalnaya-svetodiodnaya-panel-in-home-lpu-02-36vt-prizma-230v-6500k-3420lm-595h595h19mm-ip40-4690612029634-1279218/There was plenty of light day and night. Now I have no light whatsoever in my new lab. I need to get something similar going.

content: ha! you need to get an automated dentists chair (Up, Down, Recline, etc) to go along with that for your bench. That would make one funny lab.

content: Gut them and retrofit whatever you want to run in them. I mean they look cool but I prefer something like this but adjustable along with under shelf lighting.

Up until now, I have been using a modified dentist light. I removed the glass head and replaced it with one from this set in the link. It spread the light out better, and is cooler to be around so you can get it really close to things.https://www.harborfreight.com/4500-lumen-dual-head-led-work-light-64800.html?gQT=1In there standard form, these medical lights tend to be highly directional, see photo for narrow field, how did you solve that or did you use them this way?

content: I doubt you will get the same concentrated light spot with leds.The reflectors are specially designed for those bulbs.Just use it with halogens, if it was good enough for surgeons it is definitely good enough for an EE
