If I switch to 2(flood and spot) 20 W MR 16 lights, what can I expect as to burn time.
What happens to SLA if they stay out overnight during winter? I have to leave a bike at the train station everyday.
Thanks all. Charlie
edit: Maybe this should be on the geek page??
The Optronics lights (at JCWhitney) are mislabled H3 - they are actually mr16 halogen). The ones I got were 50w tinted yellow. You should change to high efficiiency 20w or 35w and get much better performance.
