Warranty

LED grow lights aren't cheap, and if you're going to pay for one you expect it to last. I've yet to have a perfect track record from any of the LED vendors I've purchased from; the lights still occasionally have issues. The same goes for any electronics purchase though, so what really matters is the warranty the vendor offers with their lights and how they back it up.

One very important consideration on warranty issues is: will the company still be around to honor the warranty? I've seen many companies pop into existence offering lights with 3 or even 5 year warranties, but then the companies disappear within a few months to a year. I can't predict the future so I can't give any advice other than:

Most of the LED vendors are now offering 3 year or longer warranties on their lights. Since one of the many advantages to LED lights is that they should last a long time, it seems to me that you're taking a huge gamble by purchasing an LED grow light with a warranty of less than 3 years, because so many other vendors offer better warranties. The companies offering 3 year or longer warranties are listed in "The Good" column in the table above; companies with less than 3 year warranties on some or all of their lights are listed in the "Short Warranty" column, and companies with no warranty stated on their website or which are lying about their warranty in places are in the "No Warranty / Liars" column.

You can see all of the warranty data for each model light in the table at the bottom of this page.

Important Details

Having a warranty on your light is meaningless if it is limited by odd restrictions; one of the now-defunct LED sellers had a "limited warranty" that was only valid if you could prove the light was never run in an overly warm environment. Basically, they could deny the warranty any time they felt like it, because you could never prove the light was kept in a cool environment all the time.

Here are some tidbits you should be aware of:

  • Advanced LED:
    • On the product pages it states there is a "limited lifetime warranty"– the limitation is that it is a 3-year full warranty, and they'll pay for parts if you pay for labor after that.
  • Apollo Horticulture:
    • The warranty is stated to be a "2 year limited warranty" but there are no details about the limitations or the warranty itself.
  • Area 51:
    • On the product pages it states there is a "limited lifetime warranty"– the limitation is that it is a 2-year full warranty, and they'll let you buy parts from them after that, if they still have them– but you have to fix it yourself.
  • Black Dog LED:
    • On the product pages it states there is a "limited lifetime warranty"– the limitation is that it is a 3-year full warranty, and they'll pay for parts if you pay for labor from year 3-5. The lifetime part comes in that they will continue offering parts and repair services at your cost as long as they can, as long as you own the light. So essentially a 3-year full, 5-year partial, with a promise to help you out after that.
  • Build My LED (BML):
    • Will only repair if at least 15% of the LEDs are out– this seems a little high to me; one and a half of the 10 crossbars on the SPYDR 1200 can be dead and they won't fix the light under warranty. I can understand not fixing a light if only a few out of hundreds of LEDs are out, but losing 15% of your light is significant.
  • California Light Works:
    • The product pages say there is a "limited 3 year warranty"; the FAQ page says there is a 2-year warranty. I gave them the benefit of the doubt and called it a 3-year warranty, but it is unclear if it is 2 or 3 years. Also, there are no details on the limitations or anything about the limited 3 year warranty on their site.
  • G8LED:
    • No details are given about the 2-year warranty.
  • Hydro Grow:
    • Different models have 2-year (Sol) and 3-year (X-Pro) warranties. I guess they don't expect the Sol lights to last as long– see the COB discussion below.
    • You must register your light to receive warranty service. It is unclear if you can do this after it breaks, so I'd recommend you register your light with them as soon as you get it!
    • The warranty only includes sending you replacement parts; you have to replace the parts yourself, or pay $50 on top of shipping costs for them to fix it for you. It would probably be cheaper to find someone skilled locally than to have Hydro Grow fix it for you.
  • Lighthouse Hydro:
    • Different models have 1-year, 2-year and 3-year warranties. I guess they just build some models to last longer than others?
    • There are absolutely no details on the warranty. If you look at the warranty information page for the details, it is "Lorem ipsum"– nonsensical placeholder text. It's been that way since at least 2012, well over 3 years at this point– I guess they just don't care, and that makes me wary of buying one of their lights.
  • Mars Hydro:
    • After 1 year (for the latter half of the "2-year warranty") they charge for labor, and will only replace up to 20% of LEDs and 30% of power supplies; if more than that break, you're responsible for paying for them. Basically, if they build a light that breaks quickly they don't have to fix it if enough of it breaks fast enough.
    • Disturbingly, their warranty details also explicitly state: Warranty coverage is ultimately left to the discretion of Mars Hydro. We reserve the right to refuse warranty repair or replacement service to anyone. So, they can choose not to honor what little warranty they offer whenever they feel like it.
  • Platinum LED:
    • Their 5-year warranty says terms and conditions apply, but these are not really specified on their site, only that each warranty claim will be assessed on a case-by-case basis, which is a bit scary since this company is just over a year old.
  • Pro Source Worldwide:
    • No details are given about the warranty.
  • Spectrum King:
    • The first 3 years everything is covered, after that they will cover everything except the "light engine" for up to 5 years. I presume the "light engine" covers the LEDs and driver / power converter, so I guess they only cover the housing and cord after 3 years.

No Warranty at All

Of the LED grow light companies in this review, only Kessil offers no warranty at all for their lights. I'd be very leery of purchasing anything as expensive and electronically complex as an LED grow light without a warranty.

Lies: Always Read the Fine Print

Mars Hydro has a 1-year full, 2-year partial parts warranty that is explained on their warranty page, and mentioned on each of the product pages. But if you go to the "Why Choose Mars Hydro" page, they promise a reassuring 3 year warranty – so they're lying about that. They used to offer a 3-year warranty, but as of the 1st of September 2015 they cut it back significantly; apparently they have too many failures to honor a 3-year warranty. They even added the disclaimer that Warranty coverage is ultimately left to the discretion of Mars Hydro. We reserve the right to refuse warranty repair or replacement service to anyone. — Meaning that they can choose not to honor their warranty if they feel like it!

Interesting Observation on COB LEDs and Warranties

COB LEDs are relatively new to the market, and I find it interesting that two of the three companies I compare that offer lights made with only COBs either have no warranty on those lights (Kessil) or offer a lesser warranty on those than on their non-COB lights (Hydro Grow). Apollo Horticulture used to offer a Purple Sun series of COB-based lights (which they offered no warranty on), but they discontinued them after about a year. Hydro Grow originally offered their COB-based SOL series with 50W or 100W COBs, but has since cut the power to 45W or 85W. Area 51's initial COB offering was 100W, but was quickly reduced to 90W.

One of the very first companies to offer lights containing COB LEDs (Stealth Grow) went out of business very shortly after putting a COB-containing product out, and I heard rumors they weren't able to honor their warranty on those lights because of the COBs even before they stopped selling LED grow lights altogether. 357 Magnum put out their first COB-containing LED grow light in 2014 and died shortly after.

While I don't have any data I can point to saying COBs aren't as reliable, the vendors seem to be saying it themselves with their lack of or lesser-than warranties, discontinuing and downgrading COB-based products — or even failing altogether. This pattern has continued for several years now, so I'm going to qualify COB-based LEDs as highly questionable, because I would be incredibly reluctant to purchase any COB-based LED grow light!
