走字灯led的选用

请问坛主和各位前辈几个问题：
1、红发红的led给灯箱带来了红色的底色，降低了对白，能不能选用白发红的led
2、有些灯箱有光晕效果，感觉不太清晰是什么原因
3、坛主有没有p10的打孔钢板
4、全户外是不是在半户外的基础上做好防水
新人刚到，请各位多多指教

手工做P10是做不出来的你想下，你打孔就是两个5毫米，中间只有2.5毫米的间隔，是很柔弱的，白发红的和红发红的只不过是做灯的时候加的色素，没有区别，那是灯太亮了，什么东西都有个度，全户外要比半户外的亮度有所提高

知道了，谢谢解老大的解答

根本就没看懂{:1_165:}{:1_165:}{:1_165:}

不知道制作发红光的LED中为什么要加进红色素，白发红不好吗

为什么红发红椭圆的就角度亮度都比无色的大
