A better beamer is a device that does just that, it extend the distance the light from your strobe travels. So while the inverse square law is still in effect, it stretches over a greater distance.

Physics bla-bla aside, it means that light coming from your strobe will go further. Some strobes, like the SB900 has an impressive zoom functions that does just that.

    There were 2 companies that used to make this product in the last 20 years. Both worked. I wanted to replace mine, but the name is worn off. Does anyone know who still makes them?Please email me at nrowe@primate.org as I probably won’t be able to find this list again..
