Re: NIGHTHAWK vs. SILVERSTAR
What about on the back of the SilverStar box that says regular halogens are
at 3200 K whereas the SilverStars are at 4000 K. Daylight is 5400 K.
Also, why on the back of the same box are there 3 pictures one of which is a
standard halogen, the other a Cool Blue, and the last a SilverStar which
shows the standard halogen as a yellow colored light, the Cool Blue a blue
color and dimmer, and the SilverStar brighter and whiter?
