That's Mars fubu. Cant believe anything they say. Just look at their par charts for ex. They're always picking up Amares crumbs. Haha, theres some fan boy acting facts.

It would be kinda strange if Mars decided to stop with the epistar silliness and make the leap to samsung 301Bs and other premium diodes... not on a 'premium version' but on the whole lineup. Stranger things have happened.

I think they will not manufacture the samsung diodes, last time i spoke with one of mars sellers and the girl told me they made their led grow lamps for 10 years, they will only make their own lights, and they told me if i hope the other chips, i must to connect to the trading companies. While I was been told their new lights similar comes soon and i probably to be the tester, they sent me some pictures and told me not speak out, but I cannot promise, if i cannot to be the tester in case, i hope someone of my friends can be, then you guys must thank me for telling the info. think probably here someone also want free lamp to try lol
the diode choice is the least of Mars product problems

Agreed. Mars has and has had the ability to make high quality cutting edge lights. They have chosen to do what they do. Realstyles had a wonderful Mars video on YouTube. They could change their business model anytime they want but have not shown much interest.

Yes the diode get burnt out on their marsII series often from i see, then they stopped the mars 700 and 1200w and upgraded the other 3 mars ii. It was pity, the mars 1200 is lamp that i like most, and now they never come back. I wish mars make more better lighting, so far the new light seems a good one.but not sure,since no chance to test it now.

You seem to have more knowledge of mars company buddy. , i always keep contact them for the new information to see any new light, new sponsorship chance, while the chance sometime is very narrow.lol

Not sure that something you said there, but their led works fine for me and the new light looooks nice and i see their IG account announced that the tester wanted, and really interest to try out the new series.

Looks alright, but when you add the driver your talking another $55- $100 on top, they don't list the diodes they use.
You can pick up a 240w QB "china copy" full kit using Samsung diodes for $155 plus shipping and tax.

Or the genuine v1 260w QB kit from HLG for $275
or the v2 260w kit on sale for $330.
Not knocking the light you linked, just not enough info on it. Not sure I like the idea of running 400w without heat sink.

HI All,
I'm trying to build out a stealth cabinet, thinking of perhaps commercializing it. My understanding is that if I can keep "lethal voltage) outside the cabinet then UL or other certification will be much easier. So, I'm trying to find a way to have the LED driver in a power brick/wall wart with then less than 40v going into the cabinet and powering the LEDs. Does anyone know of any products like this. The quantum boards with Mean Well drivers seem to come pretty close, but the voltage on low powered units seems to still be a bit too high at 49-55 volts. Any advice is appreciated

For sure, brother. You could just use 36v COB's like latest gen. Citizen CLU048-1212 or 1218. Bridgelux vero29d would also stay below 40v and can run with up to 100w. Or you take 24v strips like Samsung H-influx series(same LM301b like on QBv2). Simply connect them in parallel. You can also do strings from 3 or 5w diodes(Osram, Cree, Prolight Opto, ...); many ways leads to Rome...
Is 40v the limit for UL? 48v okay or already too much?
If you want exact these 40v you could add a few 3w diodes(purple, blue, red, deep- or far-red would make sense) to each strip or COB to fill the ends of the spectrum.
The problem with such a stealth cab is that you can't control what the users do. You can only recommend a certain voltage but a DIY'er like me would shit on the UL listing. A f.... box fan needs already 110/220v..
I don't thing the UL listing is really needed to create a valuable product. Als long as the skin is dry up to 60v is no problem and with sweat on your skin 40v can already get dangerous.

You need to know which diodes are used exactly(datasheet) to verify if the numbers are true. Also total PPF per board is important. Everyone can claim, my boards have 2,4μMol/J and without knowing the diodes you can not verify if its true or not. So take it with a grain of salt.
The Chinese like to lie when it comes to numbers and Dragonfly is for sure chinese company ...

I've Been talking to the guy who's selling them n he seems to know his lighting and I like the thought thats gone into these as well as the board size and led spacing just asked him about diodes so will see about that.
Looks like there's a v2 coming out soon n he's picking the ratio of spectrum too which I'm hoping means it's got some decent diodes!

Well just heard bk from them, thought it wld be easier to just post a screenshot of the thread!

The thing is, unless you have experience with significantly better lights you won't know what you're missing
