That seems to be the choice on the mirror "Are expensive lights a rip off" that coincidentally appeared on the Emtb forum at the same time this was posted.
One thread two forums.
So I think I'll be following that advice and maybe try a magicshine, but just the basic low lm model rather than the hi powered one. Its for road use and as Guerney said, dont want to dazzle drivers, besides the 6000/8000 are just too expensive.
I'm not adding yet another damned thing to remember to charge on my bike! Else I'd try a Magicshine (and if it's battery life was better)... To work I carry two laptops, a tablet, DSLR, mobile 4G router, bluetooth keyboard, camera flash, three phones, bluetooth earpiece, action camera+spare battery, a mobile printer, two nicotine vape pens (particularly annoying when those run out of charge!), GPS tracker light, rear blinker, USB powerbank, three LED light photography light panels, three torches, bluetooth mouse, JBL Go speaker, VAMP bluetooth amplifier+speakers (for Clannad, Nirvana and Hendrix) etc. With a multitude of cheapo lights wired to my bike battery, I could simply replace any which cr*p out, for about a tenner a time, instead of whatever burning hoops you have to jump through with Magicshine, after the warranty has expired, to get one of those fixed. And I can point my lights in any direction, creating a large (but hopefully not dazzling) spread to be noticed by drivers, or easily focus them all on the ground for tricky dark roads, showing up potholes and hedgehogs in sharp relief.
