Advice needed!!!

can someone please tell me the difference between these 2 lasers, and which they would recommend......

1 RF532-50mW-B03

2 RF405-50mW-B03S

Im guessing that the second link is a newer version.... but i want to know the key differences

The biggest difference is the colour, the RF532/405 refer to the wavelengths.
It is a green and a blue/violet laser.

The biggest difference lies in the eyes sensitivity to different wavelengths, making the green one something like 60 times brighter at the same power.

Notice that battery charger is not included, and you may want to include them in your order.

At these power levels you will need a pair of these too.

The RF405-50mW-B03S might have better divergence according to the specifications posted on the site. It all comes down to what laser color you are looking for. You cant compare an apple to an orange, but you can compare a kia to a ferrari if you know what I mean...
