I did switch to a 14.4V bottle battery on the MR16, it really still was not as bright as the LEDs I run now. It may have put out more light but it was flooding it all over the ditches and the trees. The HID I switched to had a lot of light but took 30 seconds to switch on and was very heavy (machined brass case).
