Need Some Info on MarsHydro 300-Watt LED Light

[Watergunz]

Hey guys, I need some help identifying an electrical part on this MarsHydro 300-WATT LED light.

The picture with the red circle is the electrical part I need help identifying.

Thanks in advance!

Oh, that's just the NSA monitoring chip. It's nothing to concern yourself with. Pretend you didn't find it.

Sorry, I'm no electrical engineer, just a joker.

That would be a diode.

 

[cagycritter]

Zener diode. in this case allows all the LEDs wired in series continue to function if the one LED fails. Kind of like Christmas lights. One goes out rest stay lighted.

 

[Mars Hydro]

That is our protected dioded.

 

[Mars Hydro]

yes, thank you Dominichu,

this is Zener diode，Make sure one of the broken lamp, the entire light also can work

Can anyone tell me their opinion on this light

 

[cagycritter]

Anything specific you would like to know? I am using the old style 300 watt.

 

[Growgeek325]

I'm thinking about putting one in a 36 x 36 tentwas wondering if pros and cons how it grows for only being 300 W

 

[cagycritter]

Go by the wattage it draws from the wall to make your choice. Not the (theoretical) ratting of 300 watts. I vegged in a 2' by 3' ( even though the coverage isn't optimal. the power draw listing on the data plate of my setup is 180 watts deduct about 20 watts for the fans and such your down to about 150 to 160. They recommend 30-50 watts per square foot of plant for good coverage. Hope that helps ya. I think this light is recommended to cover a 2' by 2.5' area.

That helps out quite a bit I appreciate it never grown with LEDs trying something new

Personally with led I'd go with all cool white for veg and all warm white for flower.
Mars might do some catching up and look at cree cob based design in whites.

 

[cagycritter]

I personally used the mars overhead and supplemented with cfls warm or cool per plant stage . If I could afford the crees I wouldn't have bought as I did. The Crees are also made overseas anyway.

People are killing it with cree cob diy panels.
I went a different route, not to step on a sponsor of this sites toes but I've grown with many types of lighting including led.
Whites are the way to go.
I bought 2 Rapidled onyx grows (28-cree xml2 per panel, 10 watt single emitters at 6500k) and 4 - Onyx bloom (28- cree xml2 per panel , 10 watt single emitters at 3100K), these work a charm. But still my 2 sun systems lec 315 are my faves.
