Can't tell much from the photo, but if this meter reads out only in lux you don't want it. Lux is a measurement of light intensity (I believe one lux and one lumen are the same but double check that.). All meters read lux. But rather than giving you a reading in lux, they usually translate it into an exposure setting of a given f-stop and shutter speed for a given ISO. If they only gave you the lux reading and you had to go look up in a chart what that translates into for exposure, that would be a step of about 50 years backward in the way that exposure meters work. Not sure, but a lux/lumen/footcandle meter might be used in some cinematography applications, but not generally in still photography. If you want a meter, get a standard meter. Sekonic is probably the most popular brand.
