Sharpy is a 189W moving beam light with an unprecedented brightness usually achievable only with far greater
wattages. Weighing just 16 kg, Sharpy produces a perfectly
parallel,
laser-like beam with an incredible output of 59,760
lux at 20m (5,100
foot-candles at 65 ft). Sharpy is also groundbreaking for the purity of its beam, which is sharply defined and free of any halo or discoloration around the edges.
