I am a visionX man through and through. but i also try to be knowledgable about them as well. The construction of those lights seems alright, other than a tempered glass front vs VisionX/Ridgid using high impact poly carbonate lenses. Its an IP67 value, which is also less than the big brands. IP68 being the best which is also 100% dust proof and water proof to 3M.
The Lumen value seems low for 12 3W led's, which tells me they are under driven. Due to heat dissipation qualities i would presume, but that would theoretically increase life span to under drive them. I didn't see any information on vibration resistance as well. They would be a good light for the price, but you would want to be careful where you used them. no vibration rating, and a glass front would not cut it on my rig. last thing i want to do is spend money on a cracked light bar with dead led's in it.
