What driver should i use????

what driver would anyone recommend for powering a LED Engin amber LZ1? just wondering cause forward voltage is around 2.7 or so. LZ1 Amber specs

would i be safe running 1a or 1.5a with like a standard ak-47a driver or??

ended up using a buck driver out of a cheap ebay UV p60 drop in. unsure of voltage but its around 1.5a to the emitter
