The only lihgt meter with all that we we're looking for. We love the options and different light bulb settings that are programmed into this meter.

For the price, works great. Purchased this for use in acquiring night light meter readings on roadways. It allows for lux or foot candle measurements. The instruction manual covers the quirky min/max average function. Otherwise, it did a great job on the jobsite. The included bag provides for good storage and the device is sturdy and works good in a commercial environment. The only issue is there is no back light, which made night readings a little difficult. The fact that the light meter was integrated into the device meant there was no additional wires to manage.
