The first ones you mention here are great. I bought the identical model from China off eBay. Total was about £27 which included a rear LED which was very bright too. If they break after a year as someone said then still way cheaper than the equivalent european or american version. The build quality isn't quite as good but the burn time on mine is around 10 hours on full charge. I have 2x 1800 lumens on the front of my bike and it is amazingly good.
