Some mr16 light/battery questions
So I picked up that pond light the other day. I kinda played around w/ it a little with just the stock (mr11) bulb and a 12v sla battery that I have on my bike already for my horns. First off, I LOVE the color of light that this puts out (way better than the bluish white like most leds I've had, IMHO). It seems way floody and not as super bright as it looks in the diy pics on here and other forums.
I know that the mr16 bulb (at least the spot one) will be less floody but is there another reason to get a different bulb?
Also how much of a difference is made just by over volting it?? It'd be nice if it was brighter and to have a non SLA battery (I keep worrying that I'm gonna mess this one up) but at $70-100 for the battery/charger setup, I wanna be sure it's worth it.
