Hello everyone, new member here on the forum.

I'm looking to buy some first LED lights, various makes and models to test before buying more.
I would like to have your opinion on buying used lights. Is it worth it? I have the opportunity to buy a used Mars Hydro SP3000 at 65% of retail price. I know it's supposed to have a 50,000h life, but I have no idea how much it has been used.

Thanks for your input!
