I own a cheaper Cygolite HiFlux 150 and a Magicshine. The Cygo is a better quality product in term of durability. That being said, I'm sure the TidenX is manufactor on the same or better quality. Yes, price is on the high end. If this choice was up to me, I will rather go with two lights like 2 Magicshine instead of one single unit light like the TridenX
Having two lights will offer you some insurance of not being in the dark and more versatility than one light. You can always adjust one light shining higher and the other light shining lower with two lights. If you are after lumen, personally I would choose the 1400 lumen MS light on the handle bar and a 900 lumen MS light on my helmet. If one goes out, you still have a back up. One more consideration, words out that MS might be out with a bright rear blinky that will utilize the same battery pack as the MS light making this a convient package. At the price of $85 for the 900 and $130 for the 1400 and whatever you spend on waterproofing the battery, it will still be cheaper than a single Cygolite. However there is one note, the color of my Cygo HiFlux is morre white while the MS has more greenish tint on a side by side comparison, something you will need to consider.
As for batteries goes, all rechargeable will not last forever. Price of a spare or replacement battery is $80 for the Cygo and $40 for the charger if I read the Cygo website right. Don't get me wrong about pricing, I am one of those person who is willing to spend money for goodies but cost of bicycle stuff sure can add up fast along with the fact that technology is improving so fast that one has to wonder if even investing $300 or more on a light is worth it or not when a year or two later there will be a much better light and battery setup....sigh.
