Was having a good conversation with the Gloworm Brand Manager about this whole Fiasco the other day. To be fair Ison have been very patient about this (as has Bruce @ Gloworm by the sounds of it!) because these are fantastic lights that have seen a shoddy service by the previous importer.
Can vouch for Ison doing a fantastic job with the products in the UK now, so buy one from your Local Gloworm stockist with confidence.
FWIW got to have a little play with a prototype self contained unit that they’re saying will come to market hopefully in the next couple of months. Looks like 2 18650 cells inside a body with in guessing 2 XPG’s, rated up to 1100 lumens with roughly 2hr max run time I’m told. Should be a fantastic product, perhaps aimed more at the road market, but can’t wait to get my hands on one!
