DIY with Quantum Boards

If you weren't so busy trolling you would have seen in post #7504 that Robin already mentioned they were working with 301B. That' the diode used in the Q strips your asking about.

I don't think he's trolling he really just doesn't know much about these boards/diodes

Yes we are testing lm301b. It's a flip chip design which is nice as well.

Cool. Good to know

What is the advantage of the flip chip design for grow lights?

I know who made the diodes and it aint any of us here. Anywho ill be on my merry way. Cheers yall.

@Stephenj37826 keep us Quantum board growers in the loop ! There are a few of us who constantly post grows with the Quantum's on here and have been supportive since the start.

We will be posting more sphere data soon. Really don't like to talk to much about what we are doing until I have lab data as well. Never know if data sheets can be 100% trusted lol.

Digging my QBs.

Will be at 1040w soon once I can get a couple more 3000k QB304s

I need to match them up against my 315w CMHs. I feel like that is a great light as well.

No exposed solder points. Should have a very slight advantage in the thermal transfer department. Also a lot easier to ETL without covering diodes or doing SELV.

Will these be a significant upgrade to the original QB304s?

This thread started just over a year ago... Doesn't time fly.
Happy belated birthday this thread!

Not that long when you go to the same factory that HLG goes to through alibaba com lmfao. Act like hlg does anything of their own. They are just a middleman for you idiots who dont know this. Its an american company sellin chinese drivers and korean diodes and gets a chinese factory to assemble it all....

I thought you were going to physically do it yourself thats what you said and show us your custom built boards, im no idiot sir i like many here have advanced electrical knowledge, i know exactly where they are produced and how, for myself i believe these boards are a good value and work extremely well, why cant people from china and korea build quality componets? Meanwell is an industry leader aswell as samsung. And meanwell is originally based out of taiwan not china, of course you can source orders through alibaba we all know this you are not enlightening anyone, but i still encourage you to make a product and we will see what it does but theres a reason i didnt buy wavy boards

No, he is
Everything being told to him here in regards to the current gen boards is the same stuff he was told on Reddit. Here he came across the guys that actually did the work, so he bitched out on his normal rant.

Here are some fixture I made and the next round of girls. Two are 5000k, two are 3000k and the two over the girls are 4000k. I plan on adding the 5000k to the veg room and losing the 8 bulb t5 that is there now.

What are those mounted too always looking for mounting options

Reading data sheets work?

I doubt they have better test facilities than samsung.

2-3% when top bin is fully available.... So no not really.

thats just aluminum angle, probably 3/4"x3/4" or 1"x1" 1/8th inch thick.
We used the same stuff when we upgraded my cousins CX6 to cover a 4x4

I have a sheetmetal shop, they are .10" alum with press nuts to screw the boards to and standoff's for the driver.

So, I got some info about the new 600H light ($700) on growerslight.com by HLG that holds 4x 288 QBs similar to the HLG550 with 4x 304 QBs.

It puts out more light power than the 550 but is $300 less because of aesthetic build materials and is only covered for 1 year where the 550 is covered for 3 years. It is a better bang for your buck in terms of wattage and light food for plants. Ordered mine and will be shipped soon.

I have some plants that were hit with water with high ph, I thought it had done serious damage. But they have not only recovered, they are building some damned fine bud! I decided that the best course of action was to water with some organic nutrient, so I made a solution of Grow More Seagrow ( I believe Doctor Earth is re-branded Grow More products ), ppm'd to 700 ppms. They went from mostly yellow to nicely green! I didn't think the foliage would recover!

you can see the ph damage still but the plants are doing fine!

that first plant, she's a hairy bitch lol! Never seen so many pistils. Must be the lights.....
