Most of the bulbs give off a very slight green tinge we noticed but they're very bright and we got instantly used to them. They certainly don't have the harsh blue tint that you see with many LED's. Haven't had any technical problems, other than having to reverse maybe 1/2 of our sockets wiring. This is due to the LED's being polarity sensitive, whereas standard G4 halogens are not. Easy to do, maybe 5 minutes each including unscrew, cut wire, strip, twist, solder, tape and rescrew. Considering 16 lights at 3 watts compared to 16 lights at 20 watts each, a noticeable difference in battery duration before running down.
