Ducstrom,
It appears, unfortunately, as though the site where you purchased those bulbs took advantage of you. I did a quick search for "R4 LED headlights", and could not find much information. What I did find was a few videos on youtube, one in which someone submerged the bulb in water, which does nothing for a consumer who is looking to purchase a proper kit. Another thing I noticed in the picture of the box you posted was that the label never identifies the LED chipset used in production. There are only a few manufacturers of good chipsets in the world, Phillips and CREE and a few others. All others fall short of the necessary quality to be used in Headlight production.
It's also necessary to explain the difference between LUX and LUMENS.
Lumens are much like candella, or what a single LED diode is rated in terms of brightness. When a company says that a bulb is rated at 4800 Lumens, they are rating the brightness of each Diode multiplied to get the final combined Lumen rating. So lets say your kit has 12 diodes per bulb, and there are two bulbs in the kit giving you 24 total diodes, then we say 4800 lumens per Kit divided by the number of diodes 24 is 200 lumens per diode and 2400 lumens per bulb.
LUX on the other hand is the amount of light ,measured at a standard minimum distance of 25 feet by a meter that is able to detect brightness at that distance, or any distance for the matter. LUX also depends on the housing in which the bulb is installed, projector often higher than reflector, but that's just the nature of the two housings.
