>>2321066>>2321386Im silly i forgot to mention green phosphor (gp) which is your traditional green color and white phosphor (wp) thats the light blue one. Get gp since its a lot cheaper but the benefit of wp is that its easier on ur eyes so if you have super sensitive eyes thats something to consider.
You probably would have already known this by the time you buy them if you do but just to make sure so you dont ruin it dont look at very bright shit without the pinhole cap on, turn it on during the day, or have lasers directly shine in it as they will all damage the fuck out of it.
