An appealingly small light, the Lithium Ultra still pumps out just enough power for proper off-roading. Dinotte gives plenty of light options: 3W and 5W singles, doubles (triples due soon) plus a choice of Li-Ion or AA battery packs. The 3W Ultra tested here gives the cleanest beam, with just enough light to go at decent speeds on trails you know. Run times are amazing - especially if you dim it on climbs or simple sections.
The little battery bag can be stowed anywhere and, judging by what the phenomenally bright matching back light has been through on our tests, all Dinottes are super tough and weatherproof. O-ring bar mounting is simple but totally secure and a helmet mount is included too.
Best LED Dinotte Lithium Ultra LEDs are without doubt the lighting category with the most performance potential, but there are still big obstacles to overcome. The developing technology points towards tiny, lightweight LED head units with equally tiny, lightweight batteries.
Unfortunately, stopping the largest current 5W LEDs overheating and going into meltdown is a huge problem. Reducing their power output to keep temperatures manageable means cutting back on the distance they can throw light, unless you really focus the beam at the expense of breadth.
As a result, while Cateye's Triple Shot Pro is the most impressive LED unit here, it costs as much as a HID unit and still can't quite compete with it in simple power terms.
In our view, this leaves Dinotte's tiny 3W LED light as the best example of the durability, long burn times, super compact size and weight advantages that current LED technology can offer.
