Do they throw enough light? Personally with the 700lm LEDs it's still enough for me. I do a once a week 2-2.5 hour group night ride with usually around 10 blokes, and have been part of that group for five years. The group probably has a loose membership of 25 people and the vast majority either still run Ay-ups or have done in the past. Those that have changed have done so chasing extra lumens. Despite the possum fryers that other blokes now run I can still take a turn at the front of the group and don't feel like the lack of light slows me down.
There's no question that compared to modern setups Ay-ups are under powered. However in the five years riding with group I have never seen an on trail issue with Ay-ups, but have seen plenty of others with other light brands, e.g. busted mounts, batteries dying prematurely, or piggy back cables and connections failing. My helmet mount Ay-ups still run the original half epic battery from the kit I bought back in 2006. The missus had a warranty issue with a half epic battery, and Ay-up replaced it, no questions asked with a full Epic battery before we sent the original back in. I guess what I'm trying to say is if bombproof and great support means a lot, they are still right up there. Need a mini personal sun on your bars, then go elsewhere but don't expect longevity.
