Yeah I know it was overkill,l I measured 1.18million candela out of my GT.
I bought it with the intention to swap in a 6v XHP70.2 emitter, having a quality buck driver and the 4S2P setup would lead to stable output and runtimes. Also given the larger surface area to dissipate heat would lead the XHP70.2 to be a great candidate for the GT in high powered long period illumination.
