Something i have found to be essential is to use the Monolithic Cree LEDs. (I am sure there are other brands now.) But you want a single point light source inside the LED (as opposed to lights that have several LED chips on the inside.) The multiple LEDS create shadows and artifacts that seem to be most obvious whenever you want to do close in hands on work.
Also make sure that you get true white (5000K) LEDs for your lab or you will might have trouble reading resistor codes. (Seriously)
Mostly we have simply installed monolithic LEDs lightbulbs in place of the regular ones. Dimmers and transformers in the line are what cause LEDs to flicker (usually). Be careful of "dimmer switches" they can not only cause the LEDs to flicker but can reduce the life by 90%. We have a real problem here in that the guy who remodeled the house put step down transformers and installed 50 watt halogen bulbs for the main lighting system. (Same guy that started all the electrical fires i mentioned in a previous post.) It seems he buried the transformers behind the walls and "I really don't have any idea where i put them. They are mudded in behind the walls somewhere." So i have to figure out how to get a magnetic field detector and find them. Aggggghhhh!!!
BTW do any of you guys have any idea how to find these transformers? They are about 30 years old and probably going to catch fire sooner or later.
I know it is not his fault, his mother was an innocent victim of a war time injury. But i told him "Mark, you deserve infinite compassion because it is not your fault that you are retarded. It is a very sad, very wrong, but very true fact of history that you became retarded in order to save the world from Hitler. But Mark, you have to meet us halfway, you have to remember, it is also a very sad, very wrong, but very true fact of history that
everybody liked Hitler... when he only killed retarded people."
Thanks all
