Difference between these 2 leds? (both from MarsHydro)

[HydroDyna]

I've finally decided that I want LEDs but I don't know really know which of these 2 is better if there's a difference at all.
I've found out they're a sponsor here but the bad English still seems a bit ehh..
So is the Marshydro 180W UFO fine for a 4 square foot grow box?

Thanks in advance.

Not enough light IMO. Only 22.5 watts per square foot. I would aim for at least 30 watts per sq ft.

I would also buy direct from the manufacturer: Mars Hydro LED - the Best Solutions for Horticulture and Indoor Plants You get a 3 year warranty. Not 1 year.

Thank you very much for the quick answer.
Guess I'll buy the old model 100x3W, it barely even costs more.

On a side-note, I also have an interest in growing chilli peppers are led-lights also suitable for the grow of pepper pods?

I have two of those 100x3 old model lights, they work great. I'm using them in a 26"x40" closet.

One of those lights will give you 37.5 watts per square foot in your 4 square foot grow space, so that's going to be a much better match, and will give you better results.

The LED also doesn't produce much heat, so you maybe only need a small exhaust fan to handle smell filtration and circulation, and might not have to worry about heat at all.


As for the chili peppers, I'd assume you could grow them without issues, but for any specific information, like training, light height, and things like that for growing chilis, I would seek advice from indoor chili gardeners.

They're extremely bright too. I'm happy with my purchase.
