Hi all.. I am totally new to growing and LED's.. I am seriously wanting to build my own LED setup for a 4x4 tent... Are there any basic plans and part list for that size tent anywhere ??
Cheers

Good Luck.Some Calculations:
4' * 4' = 16 sq ft
16 * 80 PPF (Flower PPF / sq ft CO2 enriched) = 1280 PPF Flower (min req'd)
1280 PPF / 2.5 PPE (PPF/W) = 512 Watts (min req'd)
16 * 60 PPF (Flower PPF / sq ft) = 960 PPF Flower (min req'd)
960 PPF / 2.5 PPE (PPF/W) = 384 Watts (min req'd)
16 * 40 PPF (Veg PPF / sq ft) = 640 PPF Veg (min req'd)
640 PPF / 2.5 PPE (PPF/W) = 256 Watts (Dimmed? min req'd)
512 W * 1.25 (Sf) = 640 W Driver
384 W * 1.25 (Sf) = 480 W Driver
256 W * 1.25 (sf) = 320 W Dimmed (?)

Notes:
1. Grow Lights should be "Sized" by Grow Area and Plant Specific Growth Stage... download/file.php?id=4438
2. Older "Watts per sq ft sizing" was based on ~ 1.7 PPE (1000W HID / 25 sq ft)... e.g., 40 Watts / sq ft ~ 68 PPF / sq ft (680 PPF / m2)
3. Nominal Efficiency of current LED Strips is ~ 2.5 PPE. The LED Driver "Sizing factor" (Sf) or multiplier used is 1.25 (125%) of the Designed LED Watts for "Reserve Capacity".
4. The -AB suffix XLG and HLG series Meanwell Drivers can be "Current Limited" down to 50% (-A) and then Dimmed between "0 or 10 - 100%" (-B), e.g., HLG-480H-AB can be current adjusted down to 240 Watts (-A, 50%) and then also Dimmed 0 - 240 Watts (-B, 0 - 100%) with a connected 100K Ohm Pot. The -B suffix Drivers are a more versatile alternative than the -A suffix Drivers, can be dimmed down to 0 or 10% (0 Watts for the HLG-480H-48B) with the added 100K Ohm Pot and (IMO) should be the only other alternative to the -AB suffix drivers if dimming is required.
