1-Power range:

10W, 20W or 100W? It determines how many pieces laser diodes are needed.

2-Beam angle:

1°，4° , 20° or 180°？It determines what kind of light path we apply.

3-Dimension:

The laser modules are small, but with heat hink, they can be heavy and big.

4-Illumination distance:

500 meters or 5000 meters?

5-Luminous flux:

What is the minimum lumen value?

6-If you are professional, please let us know the LUX value at a certain distance or the beam diameter at a certain distance.
