The Vistalite is ok for its price. I was not happy with the 5+5 watts so I went to a local electrical supplies store and bought one 10w bulb. The fact that they use standard MR11 bulbs was a factor in purchasing the light. Now I am pretty much ok.
I plan to use this setup for several years before upgrading. By then I hope either HIDs have come down in price or these newish bright led lights have developed to a stage where they actually let you see instead of just being seen.
