The problem with the SS-T 90 is it is not very efficient. You would be lucky to see a runtime of more than 2 hours and they require expensive and custom-ordered lithium ion batteries. A 6000K Xenon bulb can run for up to 12 hours on three AA alkaline batteries and still shine as bright as a 60-watt household incandescent bulb.
