Not a single reply attempting to justify the cost of lights-just a general acceptance that if it costs more it must be better-then no wonder.
I justify my purchases to one person, and I very much doubt that is you. She was so impressed with my £160 bike light that she asked me to get her one just to use as a torch.
If any justification is required, have a quick look at some comparatives (fixed camera position and fixed exposure) that I did last year...
As a base, a Cateye EL135 on its own...
The Cateye EL135 as above, outshone and outclassed as a beam by an Exposure Joystick on low...
The Cateye EL135 as above, disappears against an Exposure Joystick on high...
And, against an Exposure Maxx D on high, you can't see that the original light is still turned on...
As Cunobelin, I've spent about £500 on lights.
If you want to stick to the areas with street lights, then I reckon you are missing out on some magical riding experiences but you may find a Cateye sufficient for your needs. Riding off-road at night is glorious, riding on the road at night is hassle-free. I get 100% of cars dip at night, cars don't pull out on me and the amount of I light can produce on full power has been mistaken for a lorry.
The only reason I wouldn't buy the same again is that the 3-LED Maxx-D I bought last year has now been replaced by a 4-LED version for an extra £50.
