The ML840H Maxima-84 Hybrid+ LED light is the largest and most powerful in the Manfrotto range. A neat ''''ball head to hotshoe'''' system allows the ML840H to be pivoted, angled and turned to direct the light. It can be mounted on a flash hotshoe either horizontally or vertically thanks to the DUO feature with its two shoe attachments. This also allows multiple ML series lights to be stacked together to give an even stronger light. The ML840H can also be hand-held or fitted to numerous Manfrotto supports via its standard ¼” thread The ML840H has a flash setting, triggered by a sync cable, that emits a pulse of light four times brighter than the maximum continuous light it can produce.
