These are driver based. They have heat sinking because they will generate heat.
They are flood style. Good
They are a generic (cheap) star led. Same most likely for the current driver.
How long they last? Your guess is as good as mine.
For the price tho?!?!.. It's decent.. but I always relate back to you get what you pay for.
In comparsion to a higher quality led flood lights this is 1/2 to 1/3 the price..
My actual concern is the color of the LEDs. They are a 6000k which is a bluish white. When your looking at snow it makes it all bright white and you loose definition and textures. You would want a lower "K".. 3500k is about the color of halogen, or if you can get one in the 4-5000k they will be a lot more useful in the snow.
