Mars-Hydro LED Grow Light Discussion

[Gfcollective]

My hair is rather long, and when I pulled my braids out recently boy my hair is still coming out ha. I don't believe I have much dust in my grow area so I to wouldn't open it ever grow unless I felt like it. But i do believe there will be a good portion of my hair in there after a year of using.

Thanks doc if ur watching for teaching the bud washing!!

I should note, I haven't taken or attempted to take mine apart yet. Once a year of use hits or I get 2 of these new lights I will take my Mars 2 apart and see how easy it is.

Cofinest, believe u take them apart as well. How easy have u found it to be

Mars-Hydro LED Grow Lights Sun Series Prototype LED Light Panel

I am rooting for these lights. How long is R&D on LED grow lights? Does anyone know? When will these most likely be for sale? Sorry about so many questions.

I too am curious if daisy chaining is going to be done, maybe just not on the prototypes yet...... Sara, input?

Does anyone have an idea which color temp the white led's are for the Mars2 full spectrum light? 3000k range or 6500k range, I might have to order my own.

• Sunrise/Sunset: 2500°K
• Early afternoon sunlight: 5000°K
• Overcast sky: 6000°K
• Shade from blue sky: 7500°K
• Blue sky: 10,000°K +

Fire departments really do not like to see daisy chained power. It's too easy to overload power cords and connectors by daisy chaining.

You have to make sure the lead light has heavy enough gauge conductors to power all chained lights. Lights would have 12Ga cords and a breaker/fuse for the AC chain socket. 18ga power cords are much cheaper and easier to manage.

It looks like they are using two colrs of white, one warm which may be the 3000k range and the cool 6000k range. you can see the hue around the led itself. I think I will get one of each. Bottom right is my burnt out led.

 

[CoNerd]

A removable lens would be nice for sure. If one or more got broke or scratched it would be sweet to just unscrew and put a new one on. Great ideas flowing here.. But I still say glass would be best by far.

Why not put a plain tempered glass plate in front of the whole light? It would be nice to have something that could be put in the dishwasher to clean after each grow. Perhaps it could slide into slots on 3 sides and be secured with a keeper screw.

 

[robert63]

You can tell color temp by looking at the hue around the led. It is just like heating up a piece of metal, it starts out red and as it gets hotter the color changes from red to blue and then white. The blue and white led's use more power and run hotter than the red. I thought that was interesting .

 

[Mars Hydro]

If you watch the video, you will notice that 4 fans are blowing in, while the other 4 on the other side are blowing out. It looks like the side vents are covered with heat sinks to me. That part is a bit hard to see.

yes, one size in, one side out)))

Can someone please point me to any articles which show white light effecting cannabis bud production. Has anyone identified the mechanism of action?

I remember reading that some company was able to make white leds very bright by adding a coating like fluorescent lighting. the red and blue leds are less bright but supposedly more useful to plants. I think there is a point where enough lumens can outweigh par though.

Sara, you don't reply to my email (help to promote...) i know you have a lot of work, can you take two minutes for answer my mail , big thanks

bye

 

[Mars Hydro]

I do not think we can use this new function now, tech limited. but we will use when we can.

Sara,

Some of us would like to control our lights through something like: Milight WiFi Receiver Bridge 3.0 for iPhone, iPad, Android, and PC

The control chips are getting pretty cheap. Just wanted to put the idea in your ear.

 

[Mars Hydro]

I will forward this message to factory and get back to you what they are thinking and why they make in that waythey have a lot things need to consider in.

It seems like venting in from one side and out the other is a good design. I have 62F intake air and my roots stay pretty cool unless I circulate warm air from the lights down. I suppose if I had 80F intake air, I'd want all the heat from the lights to vent up and out. It would sure be nice to be able to contain and direct which way the waste heat goes. I'd much prefer a linear flow of waste heat than previous designs where heat flows out all sides and directly back into the intake vents.

We need to get the grow light designers to think in terms of isolating intake and exhaust and moving the heat somewhere useful rather than dissipating the heat by randomly circulating hot air around the lamp chassis.

I'm surprised there are 8, 2U fans. It seems like a retro design to me. Lots of 1980's rack mount computers had banks of small fans to both push and pull air through the chassis. They added a lot of weight and were always really loud. MH must be running these fans pretty slow in their prototype as they were pretty reasonable in the video.

I wonder why they didn't go with one long, linear centrifugal fan. It would be quieter more compact and be able to pump more air through smaller ducts. Unfortunately, they typically don't just bolt on; they have to be designed into the chassis.

The only thing I have really seen about this light that I would change is that there is no clear cover, or glass over the LED area, and they are just wide open. I hope that changes in the actual production model. Other than that, if it works good, then I'm in. Some people have mentioned an on/off switch and thats a good idea too.

how you hope to change it? please let us know if that is ok. we just want to improve lumens output, so we try our best to lose less. led chip protect well now, and you can clean it easier, beam angle is 90degree

 

[Mars Hydro]

Hi Co Finest, have you noticed that the led chip protect well, and you can clean the light , touch the chip. please check again. if we add glass, it will reduce lumens output. we do not want that.

I agree all the way with a glass lens. It is nice to have a cover so if you want to foliar feed it can be cleaned easy. Not to big of a fan of plastic lens, They scratch and there life is not that long..

 

[Mars Hydro]

Actually I talked with factory about the removable lens, they said it will be damaged easily during shipping ,so we can not use that one.

A removable lens would be nice, but then again could be just more fail spots to worry about. I just like being able to take things apart easily to maintenance myself. But the mars 1600 still looks clean in and out and it's on her 4th month

Great video cofinest! Thumbs up on the switch and lens idea

 

[Mars Hydro]

Hi Robert, its you ))) I did not know FEDEX can not delivery to your home, I have asked Lucy arranged shipment for you by EMS, the former replacement parts will be destried and we need to pay 31.9USD taxes. you said you want to buy led yourself, and you asked lucy the specs, the led we are using is customize one, you can not buy on market, we have to ship from China for you , much higher cost than you buy on ebay or local store. but we would like to , because we know you can not find the right replacement parts.

Hey everyone , I have a question, What do you think is a acceptible time period for waiting for replacement led and diode for my Mars2 light? Still under warranty. Going on 6 weeks, still no parts.
