How much light do you have in your lab?
<< < (3/7) > >>
SilverSolder:
I just checked the lab area with a good quality light meter:   250 lux ambient light.  This is subjectively pretty bright to me (white ceiling, white walls, light carpet).

The desk work lamp is 18" wide, with 2x fluorescent tubes, on an articulating arm.  It casts 1300 lux of daylight over a wide area on the workbench when 24" off the table;  because it is so long, it doesn't tend to cast shadows (light from many directions).  It can get much closer if something really needs to be lit up - 8000 lux at 5"!   8)

Ever since my cataract operation (both eyes) I agree with you. I find that I am much more light sensitive now and that 350 lux is ample light for the general surroundings.
Blue and near UV light sensitivity is out of this world, like getting your 20 years old eyes again...

And your boss accepts that? I assume that in Germany during the winter there's no daylight for eight hours plus the lunch break...

We're not that far north. Apart from rainy days, it's bright enough during regular working hours. Main light in my current office is also rarely on during daytime.

My eyes have always been exceedingly sensitive to light, too much light can be overstimulating and makes me feel like I'm exposed out in the open or being interrogated by the gestapo or something. For whatever reason being surrounded by darkness makes me feel cozy, I don't much like wide open spaces and prefer a secluded corner. I suppose it's a bit like how cats tend to like to curl up inside those little enclosed huts. Oddly my first word was "light" and I've been fascinated by light bulbs and lighting technology since I was a small child, I like lights, I just don't like being in a brightly lit room.

I have 10 industrial Organic Response LED light fittings each with movement detectors. Around 250W of LED lighting all up if everything is on full. The lights communicate with each other with IR and adjust their PWM intensities according to what I am doing. I installed them in the ceiling at carefully calculated locations to eliminate shadowing. I programmed the lights' behaviour using an IR remote control. I also have 96 mains power outlets built in the wall. In my office I have 32 mains power outlets built into the wall. Add to that comprehensive climate control, and I have a great ecosystem of for working in the lab and in the office.
