Volts (V), Amperes (A) and Watts (W) are all units of electricity.
V = W / A
A = W / V
W = V x A
Everyone knows how bright a 100 watt light bulb looks. However, watts aren't a good way to tell the brightness of a light source.
Things like bulb quality, materials, the inert gasses inside the bulb (Krypton or Halogen) and the reflector and lenses make a big difference in light output. The units Lumen, Lux and Foot-Candle are used to determine actual brightness. You could purchase a Lux Meter or just come into our shop and try out the lights in person. Many of the new LED lights are amazingly bright.
ABR has a working display where you can try out all our lights. Heck, we will even turn out the lights for you! Or try them in our dressing room with the lights off.
Our staff commutes by bike all year long, so we have firsthand experience on what works.
