I am indeed interested T.S.G .. your a good egg for sure!if you dont get the hook up , ill be using an American address if Heisin decides not to do international straight away if your interested man
sweet man well just see if Heisin wants to ship testers international or not.I am indeed interested T.S.G .. your a good egg for sure!
I'll gladly pay the freight and test and post a journal here If u need more testersI can ship internationally if you guys pay for the shipping. I think discreet shipping through UPS is the best way to do it . In like a Tshirt or a CD case or some other way similar.
No problem. I'm gonna post updates here and go through this thread as soon as the seeds are ready. I'll add a list of names and get everyone's address so all the seeds can go out.I'll gladly pay the freight and test and post a journal here If u need more testers
sweet i have no problem paying whatever shipping costs neededI can ship internationally if you guys pay for the shipping. I think discreet shipping through UPS is the best way to do it . In like a Tshirt or a CD case or some other way similar.
Remember when Canada had the best u could get? That day has past and won't return with guys like Heisen Cap and many others who have really stepped upsweet i have no problem paying whatever shipping costs needed
It seems like people have to be a little more discrete nowadays.Seemed to never fail to just throw pks in a bubble mailer,and you always got them..they want to lock us down to just the "legal" gov't junk.You have the right idea @Heisenbeans ,include with something
Yeah, there's a video on YouTube. He used a hlg-600 driver and pumped it into a qb288. It did fine until I got up to around 670 Watts. It didn't burn up or anything it just stopped working at that point. So I think it's safe to say that these QBs can take four times their rated wattage. The qb132s and the qb120s have even thicker and bigger PCBs because they are designed to run without a heatsink. So, I believe they could take even more than thatQBs are legit as they come. I think ledgardner pushed like 7amps through one. Or something really high. Way past max. Jus kept going. Then it finally jus went out.
Hlg exaggerates when they say the hlg 550 can replace a 1000 watt single ended HPS. Keep in mind that that fixture uses the 480 watt driver. I don't remember where I saw this, but if you look at the par/ppfd readings, it really takes 775 watts of QBs/strips to equal 1000 watt single ended HPS. People say we need 30 watts/sqft for QBs/strips, but, in my experience, you're better off in the 40 watt/sqft range.cool thanks guys, you have made up my mind for me! I think I will be happy!
last question, will I notice any difference in yield or density of my nugs? coming from hortilux eye 1k hps! the good bulbs lol! I've read the 550, will replace 1k single ended, but the 600 will replace a double ended hps! makes me think I'm looking at a possible increase! as long as nothing is a decrease in weight or density of my buds I'm happy, don't need an increase regardless of how awesome that would be!
You are right about the potential for thermal runaway. However, since these boards can take four times their rated wattage, or more, I don't think it's a concern. Plus, I haven't heard of a single instance of thermal runaway happening with boards or strips since these things came out. But you are right, with parallel wiring on a CV driver, the risk of thermal runaway is there.I know your right about that but wrong about runaway. Parallel wiring each group to the driver has a greater chance of it than series.
Everything I have read on parallel led setups warns against it without resistors.
How can it not be when none of the strips share the same current only voltage
I'd like to do a combination of cobs, pucks and strips. I wonder if strips would be good for side lighting in a tent, lining the walls so far below plant canopy. Being almost cool to the touch.I dig my Growmau5 pucks
I'm down with that, especially if it's some bad ass heisen beans tshirts!!! have you thought about getting some made! I'd dam sure send some cash now for one of them!!!! @HeisenbeansI can ship internationally if you guys pay for the shipping. I think discreet shipping through UPS is the best way to do it .

Not so much an issue with meltdowns as it is with uneven lighting. I have my boards setup to run in series.You are right about the potential for thermal runaway. However, since these boards can take four times their rated wattage, or more, I don't think it's a concern. Plus, I haven't heard of a single instance of thermal runaway happening with boards or strips since these things came out. But you are right, with parallel wiring on a CV driver, the risk of thermal runaway is there.
I prefer using constant voltage drivers and wiring in parallel because it's easier to match drivers with groups of boards that way, plus you can be sure to be able to use the max potential wattage of whichever boards you have.
