今天把收到的4个氙气灯泡剪短引脚后一个个插入我的GP灯头试了一下,分别是12V1.25A,9V1.35A,7.2V1.2A,3V1.6A,按照额定电压点亮,前面3个亮是亮,不过是那种一亮一大片,距离稍微远一点,光斑就变得很大,从灯丝的长度上也可以看出,GP灯头的反光碗对这种灯泡来说是小了点,我把灯泡塞进投影机反光碗里试了一下,就很爽了,距离7米多,可以形成一个很圆的中心光斑,又白又亮,而且光斑直径在30cm左右,3.6V1.6A的灯泡灯丝稍短些就比较合适用于替换5R灯泡,光斑亮度没有5R亮,但也已经很不错了.<img src="attachments/dvbbs/2005-8/2005817222997684.jpg" border="0" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor=\'hand\'; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onclick="if(!this.resized) {return true;} else {window.open(\'attachments/dvbbs/2005-8/2005817222997684.jpg\');}" onmousewheel="return imgzoom(this);" alt="" /><br><img src="attachments/dvbbs/2005-8/20058172241960881.jpg" border="0" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor=\'hand\'; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onclick="if(!this.resized) {return true;} else {window.open(\'attachments/dvbbs/2005-8/20058172241960881.jpg\');}" onmousewheel="return imgzoom(this);" alt="" /><br><img src="attachments/dvbbs/2005-8/20058172264540747.jpg" border="0" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor=\'hand\'; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onclick="if(!this.resized) {return true;} else {window.open(\'attachments/dvbbs/2005-8/20058172264540747.jpg\');}" onmousewheel="return imgzoom(this);" alt="" /><br>原装5R灯泡,看上去灯丝长度和这个差不多
