Gather suggestion on our new line products

[Roger A. Shrubber]

even if they used actual wattage, that still really doesn't tell you a lot.

My first suggestion would be to not get suggestions from an internet forum. The majority of responses will just be repeated rhetoric of the day and often skewed towards one set of technology or vendor over another.

You are better off getting an LED designer to help since they actually have an education in light and can work within the specifications you give them.

Lastly, if you are a manufacturer and can do large volumes (eg. greater than 1k/month) you don't need to go with brand name chips like every small scale DiY kits and part vendor does. With those volumes you can get chips far cheaper than the deepest brand name discounts and as a result put down more of those chips resulting in more light output at less power. The only thing that matters is light output, don't stray away from that.

Now if you are just small scale consider yourself as chum in the water right now.

Now days education is learned online through these forums i am in usa and its pointless to go to collage right now. Not till it actually has a purpose. Its about the never ending search for knowledge and experimentation. To be honest.

I do see what you mean though because one wrong person giving out bad info can cost hundreds if not thousands of hard earned money.

That is the reason you use a professional. If it doesn't work out, you can sue them and the professional associations that validated the person. Never gets that far as insurance kicks in.

Going with jo-schmo or internet info gets you nothing in the end if it doesn't work.

Plus a light professional would look at the Cree horticulture reference design and has access to other research to come up with your best options.

 

[Nugachino]

It would honestly be refreshing to see a maker not dribbling bs about their unit's actual power use. I don't care what it's supposed to replace. Just tell me what the wall draw is. And give me accurate ppfd figures.

No bs. Just facts.

Agree if they get someone with the tools. Hell ya!! Make one hell of a light with actual test reports.But that stuff i believe costs thousands of dollars. Doesn't help either that a lot of companies copy or fake test reports. With that being said Geyapex Technology test your stuff release actual test reports will help your marketing.

Hey plant lobbyist. And info if it is possible to use a rsp-1500-48 for 24 cobs?

 

[licoricetree]

Hard to get info on this.

To put a good one on staff is around 250k/year. But it is worth it when you have a large number of fixtures.

For a single light design is might be 2-5k or even less. Then you need to fork up the money for a prototype and testing.

Hey plant lobbyist. And info if it is possible to use a rsp-1500-48 for 24 cobs?

Anything is possible. For this case, you would need some converters since it is constant voltage. Similar to how people use bucks and converters to use common PC power supplies. So yes, it can be used. But is it worth all the extra hassle?

Good to know ya probably not. Do you know any viable drivers higher than the mean well 600h? Would you need a converter if you set the voltage to 52v and run parallel on 24?

I wouldn't run that much off one driver but that is just me. For the most part I try and go either 1, 2 or 4 cobs per 50w driver with quick connects so I can easily move them around.

 

[licoricetree]

the bigger ones seem to be better for parrelel cause even if 4 fail you dont go over watts or amps. So no converter would be necessary and i could essentially hook it up like i would a normal hlg driver?

 

[Plant Lobbyist]

For driving hard, yeah they would be better. I go the other way with under driving so I can't really help you.

If you want a lot of instantaneous light and aren't impacted by efficiency then over drive all you want. For efficiency you want less heat generated in relation to the light output. Both go down as you lower the current but the heat goes down faster till it reaches equilibrium with your ambient temps. Without super cooling, you aren't going to get much more efficient than that.

Don't need converters, output voltage is programmable 43-56V on the RSP-1500. http://www.mouser.com/ds/2/260/RSP-1500-SPEC-806383.pdf

You should totally change the design.

Use more and better COB's like the Citizen CLU048-1212C4 in 3,000°k and 5,000°K in a 2: 1 ratio and use blue and red/deep red/far red only to supplement the COB spectrum.
If you have not used cheap Epistar LEDs so far, a design change in this direction will reduce upfront-costs and reduce error sources!
The 1212C4 is really a great and efficient COB and you will get it in higher amounts for sure for less than 8-9$. It outperformes the CXA2540 easily and maybe also the CXB3070 depending from used binnings.
There is no reason to drive so many monocromatics unless you use cheap chinese diodes, but in this case your company will anyway fail in the near future, unless you change your mind and start building high quality products "with HQ diodes".

Rather than following the crowd I would recommend being innovative and separating yourself from the pack. Margins on these things are not going to be great as competition heats up and the tech is currently advancing so fast that by the time you've sunk your money into it, someone else is coming out with a more efficient or cheaper design.

What are you talking about suing people if "it doesnt work out"? If what doesnt work out? The light?

Also, where do you think these professionals go to obtain this research? Answer, the internet most likely.

You realize hes not tasking us with building the light, simply getting ideas for the specifications so he, or someone else (the professional you speak of) can actually make it. Just because someone is a professional in the LED field doesnt mean they know shit about growing or the needs associated with it.

Ok just as i figured awsome. I have an idea for a big area but i dont want multiple drivers. So im thinking

In a large production scale if something goes wrong then it affect all the product that were released with it. IE samsung note 7--what was that like a 3.2 billion dollar loss
