I have a Nissan NV200 cargo van, the cargo area is lit by a single incandescent bulb near the rear doors. To say the cargo area is dark in an understatement. I was sorely in need of a lighting solution. I researched the net, read all sorts of reviews. The major complaints were LEDs that simply weren't bright enough or there were premature failures.the Bluefire two pack caught my eye, first was the price. it seemed to be a lot of LED for the money. Second the reviews didn't mention poor brightness or premature failure. (I always read the most negative reviews first looking for potential disqualifiers, I found none)The product arrived in a timely fashion, upon unboxing the product I was struck by the quality construction of the unitespecially the LED driver circuitry. I did a quick bench test to insure both units were operational. The light intensity was beyond my expectations as was the color temp of the LED's. I find that the "cool white" can be overly blue , akin to a Christmas light, the warm white sometimes has a tendency to run far to orange or yellow. These units were a nice neutral white.Installation, The supplied screws were a bit inadequate to screw into the van sheet metal. I purchased a few screws from the hardware store for .50 and all was well. The wiring instructions were a bit vague, but there was a mention that these units are NOT polarity dependent. I wired the two units in parallel into the vans door lamp circuit, dressed the wires neatly and job done.I now have a very brightly lit cargo area, I'm pleased with the overall look. And would heartily recommend this product.The only area I can't comment on is durability for the simple fact I've not had these units for any appreciable amount of time. Get back to me in a year or so and I'll update this review
