  After personally experiencing the problem of eyestrain with our new LCD monitor I did a little researching to find there are many effects fluorescent lighting (flickering) can have on an individual such as straining the eyes and inducing headaches. Include also the electrical ballasts used to operate fluorescent lights and the known
‘dirty electricity’ that they produce. What we found is that this health problem with flat screen monitors is becoming more common than people think.
   Because of this issue and to help reduce the eyestrain we have decided the to take apart our LCD computer monitor and fit it into a wooden box that allows the screen to be illuminated with LED’s that operate on direct current (DC).
   A quantity of eighty LED’s will be used. Each LED is 10mm and rated at 290,000 mcd brightness. Expected lifespan of these LED’s is 100,000 hours.
