I've been an Inova/Emissive Energy customer for years and have bought probably dozens of their lights, from the original spotlight X1 through T0n and X0n series lithium-battery lights, to the 24-7, X5, Bolt and Radiant series, etc.
I called up Nite Ize today to have fairly new (about a year old) Radiant warranted. Of course, like all Inovas, the Radiant has a "lifetime warranty".
I was informed by Nite Ize that this product was no longer covered by warranty since it was no longer manufactured (even though they acknowledged that the product is still sold new!). Their only offer was to give a 40% discount off of MSRP of another Inova product.
I find this to be really ridiculous, and something that Emissive Energy would never have done when they still owned the Inova line- I've had absolutely great results with EE customer service and they've gone out of their way to keep me a satisfied customer, warranting even their oldest lights without a single question.
I figured that when A) Company X is bought out, and B) New owner Company Y won't honor warranties, that inevitably C) will follow; moving production to China. I did inquire about that and was told that yes, in fact, production of light parts would be moving to China. Sounds almost like Novatac ;-)
At any rate, be Very Very careful if you're thinking about any Inova lights- the "lifetime warranty" isn't worth the paper it's printed on- and they're about to become yet another Chinese brand, except probably without the innovation seen from Fenix or 4-7s, etc.
