I think theyre all 100K Ohms.If I build a light with 6 boards on 3 HLG 240-1050b series wired what potentiometer needs to be used? Thanks in advance
If using 1 potentiometer to control all 3 you'll need a 33k ohm.I think theyre all 100K Ohms.

WAAAAAAAAAAH!!!!!!!We need some pics of flowering plants today and tomatoes will not cut it. This idle chatter bores me. I want QB board pics over flowering plants.
Lol, just went in there checking on things and didn't bring my camera. Leaves are staggering with nice young buds. I've been trying to Doctor one of my plants though as the FFOF was off. One other thing I noticed is that the bottom fan leaves are facing the sides of my tent and nicely taco shaped telling me two things. One the light penetration and spread is amazing bouncing off the tent walls. I'm sold on what I'm seeing so far. Jury still out on a complete flower harvest but have no doubt it will do the due.We need some pics of flowering plants today and tomatoes will not cut it. This idle chatter bores me.

That's what I'm doing with my A driver, using the internal pot to dim. The external dim drivers may give more spread though, not positive.Ok, so im going with 4 quantum's on one driver, the A driver uses a internal dimmer? Dont need pot
WHAT?!?! Blasphemy!Ok, so im going with 4 quantum's on one driver, the A driver uses a internal dimmer? Dont need pot
Doing up a bowl of gg4 bubble as i reply.WHAT?!?! Blasphemy!
yes you can do this tooWith the 320-1400, NGL engineering page shows a 2 parallel + 2 series (2p+2s). Can this be furthered to 3 parallel + 2 series (3p+2s)? If I understand correctly the Vf is the same just the current is in thirds instead of halfed.
If correct, the 4 qb's (2p+2s) would be @ .7a, so 6 qb's (3p+2s) would be @ .466a, roughly 48w a board?
No plans to stock drivers as there are so many options. We can consider stocking 1 or 2 drivers if they are popular.1. If someone does DIY with the board and the pads, coming back into stock, will you be selling drivers/ballasts or do you recommend someone?
if it is 110.1V @700mA then it should be around 115.9V @ 1400mAwell my board did run 110.1V @ 700ma so wondering what the upper end of voltage they need.
here's what i am thinking that my board is a voltage hog so it run more V cause at 130v *1.400ma gives me 182 watt and with driver loss.
silly ? how do i work out it's lumen per/watt now.
We did the calculation few pages back. The max driver current for board is 1600mAso now it says max is 1400ma when i am pretty sure it said 1600ma before.
ok sorry so whats the max Ma and voltage for these boards hoping right now that i am not pushing it too hard
edit and when you mean the A version give more power as in milla amps
i guess it would have to be wouldnt it ?
What will the slate(xx) price be?Original Heatsink (side view) SLATE 1
1.85Kg/Meter density
100+ pcs of 'slate 1' expected to be air shipped to us next week so will stock in 10-14 days.
60+ pcs of old 'slate 1' heatsinks in sea shipment expected to arrive in 4 weeks
New Heatsink (side view) SLATE 2
2.4Kg/Meter density. Taller and serrated fins for boards running at higher power.
New heatsink will be ready in 10 days. should be in stock end of this month.
View attachment 3870411
Hole patterns will be same for both as board size is same.
New 3X Board heastink using same extrusion as SLATE 1, just longer. SLATE xx
Limited samples of new heatsink . same extrusion as 'slate 1', just 3 times longer to fit 3 boards on single heatsink. 10-14 days.

We might call it slate 1.3What will the slate(xx) price be?
How did you arrive at this number?If using 1 potentiometer to control all 3 you'll need a 33k ohm.
