The OSTS doesn't drive the LED as hard to get the performance, Vinh's stuff is more souped up in that regard.
Its a little like a race between a muscle car and a Lotus, etc. Its two different approaches to an end goal.
The run times will tend to be better on the LED that's not driven as hard of course, and Saab does certify each light, and gives an across the board estimate for the mod. Vinh gives an estimate across the board for a particular mod. With neither do you KNOW exactly what you will receive as far as final specs, and whatever you get, is what you get. With Saab's, you know that when you look at the card in the box. With Vinh's, you know if you measure it yourself...or, you just DON'T.
I would not say one is always better as a blanket statement. Cost can be a factor for example. I would say that you would chose based upon what way of getting there works best, for you.
I have some of both....and, am happy with all of them...as they all do what I wanted that light to do.
Thanks for the great explanation.
