Yes, this grow light does have a warranty period: that of three years. This is quite impressive as most grow lights usually offer you between one to two years, but brand Viparspectra has always been known to be one which goes above and beyond the generic brands and offers you with an impressive three-year hassle-free warranty. On top of that you also get a thirty-day return period in which you can return the product back to the manufacturer if you are not happy with the performance and get your money back. All of this put together makes Viparspectra one of the best brands of grow lights out there.
