The Intova, and probably the DRIS , are most likely versions of a number of dive lights coming out of China using the latest CREE high output LEDs, which can do between 800 and 1400 lumens. The generic lights can be found on ebay starting at $35 and use rechargeable 18650 li-ion batteries for the most part, which will probably give them much longer battery life than Cs. It's disappointing that both companies are rebadging these lights and marking them up 200 to 300%.
