"Somehow I doubt that this is something accurate - throughout the entire range, or durable. In less than a year the (Original Poster)and manufacturer will probably be long gone"
I might got me a Lifetime Warranty.
CREE light bar products are so inexpensive the price seems incredible. Especially since they use a 7.2 voltage regulator. Yet they keep shining.
I purchased cheapo voltmeters that are a full tenth of a volt bad so the accuracy and durability issue must be resolved solely by actual experience. In 20 years I have encountered "E Meters" so laughably in error that I had to bite my tongue to not insult yacht owners about their $300.00 waste of money. A seven percent ampere hour error is not insignificant.
