ok ok don't get this nipple thing going again, it doesn't make a difference on PAR output (I have tested this my self as well as several other big names in the US)
Chin Lee, I could see if your metal frame is causing a slight shadow then turning it might make it brighter but most people would never notice that at all. could some other conditions have changed during the time the bulb was off for you to change it? or could it be a illusion as it was off for a while to cool down and then to restart after you switched it so it seamed brighter?
