To measure Lux, you need a lux meter. Since the output of light varies to the distance, you should measure at a standard distance for both sources and over the same surface area. You will find out that there is a relationship between lux and distance.

Your led lights may have:

1. different output intensity by led type.

2. different reflection pattern and lenses. Form and material of reflector.

3. color and color temperature may be different.
