What is the light output in lumens? Wattage for LED is not directly comparable to wattage for incandescent lights and is meaningless.
As a basis of comparison a H7 bulb is typically about 1200-1400 lumens from what I have read. My generic branded, chinese made, aux LED lights are spec'd at 4000 lumen each and decent quality and are extremely bright. I would be concerned if they are unwilling to list the light output in lumens. To perform well these lights should be 3500 lumens/each or higher and be focused for a narrow beam (to get distance down the road). After purchasing my non branded LED aux lights from AliExpress, my opinion is that Denali and other big name brands are grossly overpriced, especially in light (no pun intended) of the continuing decline in the cost of LEDs. It would not surprise me if the Denali's come out of the same Chinese factory before they have their name stamped on them.
