I have had problems with the OHs. First I bought a 4000 lumen OH, but I
had to turn out all the lights and even then the screen was not bright
enough at times. I tried several different OHs but ended up with an 11000
lumen OH that is very bright and I only have to dim the lights a little, but
dimming is not neccessary.
I use the LCD on a daily basis to teach geometry.
That is why brightness is important to me.
