2019年11月2日 · Hi everyone, i've been a lurker for quite a while here and seeing more and more grower switching to LEDs! I'm in the process of upgrading my old 250watt HPS grow light to a quantum board and was originally looking at the samsung lm301b diodes but while I was researching I learned that Samsung...

2021年6月5日 · Depends. Is not that easy to answer as peope think. Forget that "165 vs 220" lumen/watt BS. First you need to bring every diode to the same current. There are LM281B+ top bins, that reach 200+ lumen per watt and there are 301s that dont. If you compare the best LM281B+ bin to the best LM301 bin, the LM301 puts out 13% more light.

2021年6月5日 · It's interesting topic and there is another parameter forgotten, you cannot look only the 165 vs 220 lumen per watt, keep in mind one has a rated power of 0.2W (LM301) and one has a rated power of 0.5W (LM281B) , so ok it has a lower lumen per watt but you basically need 2 for 1W and you need 5 LM301 to make 1 watt , so to reach the same rated ...

2021年1月11日 · The samsung lm301 is way more efficient than standard SMD LEDs. The number of led doesnt matter as much as the overall wattage. Some leds use .25 w some use .125 some use 1w. You want 30 to 35 watts per square foot for leds. Samsung lm301 LEDs are currently the most efficient leds you can get. Nothing is better right now.

2024年5月4日 · Yeah I haven’t had too much of a look at them yet…..i was looking at only a 3x3 tent but with everything that comes with a 4x4 kit that you create your own on Spider Farmer & i was looking at getting the G5000 450W but then only now i realised they run Bridgelux diodes & i know all will work well enough although the efficacy of 301H Evo outdoes every other style diodes in many aspects imo ...

2022年7月8日 · I’m going go get a 4x4 tent but I’ve only got 2 100w sf1000 from spider farmer. How many watts would I need for 4 plants in a 4x4? Should I get a 200w SF2000 to make up for the extra? I will also be flowering with these lights

2021年2月11日 · The specs are very similar. They both are using the Samsung LM301 diodes. SF is using the B model and VS is using the H model. From what I have read they are essentially the diode but the B is the original and the H is the “horticulture” version with very minor differences that really only amounting in a little more efficiency.

2021年11月7日 · I have 2000 watts LED (LM301 from Bestva) for each plant and keep the light at approx 5 feet over the top of the pot. I use 2 1000w lights and not a single 2000w. I use 2 1000w lights and not a single 2000w.

2018年2月26日 · What lights and medium are you running? From what I'm seeing, Masterblend needs more magnesium in coco under Samsung lm301 LEDs. They seem to like 2-2-2 better. The 2-2-1 works great for veggies tho under LEDs.

2023年1月26日 · You’re better off with lm301 h or b boards or bars. Dbean16. 21 3 Jan 27, 2023 #3 Oldguy71 said: I’ve ...
