Pulling the trigger on one of these soon and wondering if anyone has anything to say about either.

I thought spider farmer was the one prone to releasing all the magic smoke? Karma is right about MG, lots of people have them, have seen zero complaints. No personal experience, full disclosure.

Spider Farmer, and Mars Hydro, are both part of the same company.

So, I went with the MedicGrow 8. Super bright and fits just barely in a 4x4.
The MG8 uses Samsung LM301Z's and there's a real heat difference from my LM301B fixture.
The center bar gets up to about 130F at 100% and the light bars vary wildly but the hottest I've recorded was 140F. Most run 125F-135F.
I've compensated with a ceiling mounted fan and by using the highest vent fan settings.
All in all I'm really impressed with the light readings I've taken and with the construction on the MG8.
It's a lot of light for $470

thinking about getting the mg8 for my 4x4 today. by ceiling mounted fan, do you mean just one at the top pointed at the light or what?

I have a fan blowing across the power supply at the center of the fixture from above. I heard that keeping it cooler could extend the life. Maybe...I dunno. The 8 just fits a 4x4 and I haven't run mine above 80% so far. The readings are solid there and the heat problem is reduced. Summer in south Florida makes for a hot grow. BTW, I came across a nearly new Mars FC8000 right after I bought the MG8. I bought it. It's a cooler light and the separate power supply lets me put it near the exhaust. I'm impressed by both but the Mars is also easier to hang so I have to say it's the best if you don't judge on price.

I had a mars fce4800 next to a samphon480(same manufacturer and lights as medicgrow just different branding) the mars had a warmer spectrum and grew better quality than the cooler spectrum light.

Stamping a letter code on your light doesn’t make it fire resistant.
You want proof? Okay…

Theres been a few of these, both mars and other, usually with these waterproof quick connectors. Ive never had it with any diy connectors, even AliB/china, but ive had brunt out china wagos.Stamping a letter code on your light doesn’t make it fire resistant.

Sounds like you've done several loops with these already. Do you grow where managing heat is ever a problem? Did you notice any differences in the lights involving heat?

man that is brutal because I really want a safe LED light. It felt so good getting away from HID because of bulb temps being a fire hazard, i'm not always home and a connector burning up like that is a huge concern

I always rec build your own, then you know the parts that go inside and can decide yourself. I dont mind china boards, especially ran soft, but driver and connectors/wagos i get locally where i trust the gear. I keep on saying it: the best part is the sense of achievement when you first turn on your lighting project, followed by the first time you beat your yield record.
Another thing you can do is to solder your connections rather than just pushin connectors.

I did not see any real differences between the two heat wise, but I’d suspect the Gavita would push out a bit more heat than the Medic- since it has so many more diodes. While growing under LED’s, you want the heat at 80-82 degrees in the room, and 85 degrees if using co2- so more heat can be your friend.

Used a Mars for 3 yrs nonstop. No fires, not so much as added heat to my room

I’m glad to hear that yours gave you no issues.
There have been documented cases of Mars Hydro LED’s starting small fires in the past.
Luckily, nobody’s house burned down.

Okay, if that’s true, show me an example, like the one I posted above of a Mars Hydro light catching on fire.
I’ll wait.
