<p>I know that this is a very weird question, but the light bulb on the fan in my room has always been 60 watts and then i switched to 100 watts and i notice an incredible less strain in my eyes while studying and I comprehend material much better as well as not feeling sleepy until about 1 or 2 hours later into the night.</p>
<p>Ideally, lighting should be as close in properties to that of the sun’s own light. Full spectrum (5000K + color temperature) or fluorescent lightbulbs which produce softer whites can be used. Having a ceiling light right above you will minimize glare and shadows. </p>
<p>It’s not voltage so much as it is wavelength and color temperature that affect lighting.</p>
<p>I like studying in the dark with night vision goggles</p>
<p>I don’t use my eyes when studying.</p>
<p>^ You buy ther braille version of your textbooks too?</p>
<p>I don’t use textbooks.</p>
<p>Right now, I’m using 40 watts, which is working okay for me, but it can get a little too dim. I started with 60 watts, which I think worked well for me. I did switch to incandescent light bulb that was supposed to give out a natural ambient light at one point, but I don’t know I kinda got sick of it. It was really bright. </p>
<p>I don’t know I just can’t study in bright lights. There’s also this thing where I need to block out certain areas of my room (b/c the mess drives me crazy lol).</p>
<p>I study by the glow of my computer screen.</p>
