Your store is indoors, but windows face east / south → 1000 nits works.
Glass window with zero shading, or semi-outdoor signage → go straight to 1500 nits.
Not sure? Order a single 1000 nits unit as a sample. Test it on your actual window. If it’s not enough, we’ll help you upgrade to 1500 nits (custom brightness is supported).
