Review on Colight 9610A-8 inch LED Light Bar: 30W 1pc Single Row Driving Light for Off Road Adventures - Cabin, Boat, SUV, Truck, ATV by Pauly Blake

If your assembly tolerances are critical, this light does not match the description in the advert. I also bought a light panel as a precaution - the delivery times were a week apart and I needed the light as soon as possible. This lamp was called the "6D" lamp cup and cost $20 more than another with a "4D" lamp cup. They both arrived a day apart, not a week apart - great shipping! Both were packaged very similarly and when I opened them they were identical products purchased from two different vendors with different names. What was frustrating was that you had to pay more for supposedly more efficient lighting, and parallel testing made no difference. Now I have a spare and have run out of extra money, lucky me.
