LM561c vs LM301b vs EB Gen2
Posted: Tue Dec 19, 2017 11:55 am
Hello, forum
I am new here, so good day to you
For the last 2 weeks I've been researching appropriate LED lights for vegies. I do have experience with T5 HO LEDs (3900 lm, 26W) and they give me great results. I would like to not depend anymore on the internal drivers of these tubes, as they might start switching on and off uncontrollably in a foreseeable future. I want to just need to replace the said drivers, therefore is easier with rigid strips (it's nice to use said 50.000 hr life LEDs when shitty drivers don't come into play).
I have 3 options and would like to get the best "bang for the buck". I want to use them at the test parameters to get the best output.
1. LM561c H series B8R221B2HUS. 1120 mm, 5000K, 960 mA/22.5 V (~21,6W), 192 lm/W - 4156 lm, 200€ 10 pieces
2. LM301b Q series B8R201B20US, 1120 mm, 5000K, 450 mA/43,8 V (~19,7W), 203 lm/W - 4000 lm, 186€ 10 pieces
3. EB Gen 2 BXEB-L1120Z-50E4000-C-B3, 1120 mm, 5000K, 700 mA/37 V (~27,3W), 180 lm/W - 4920 lm, 118 € 10 pieces
I will need 8 strips, 4 per shelf, but will get 10 to have some spares. I see in the data sheet of the HLG-100H-48 recommended by LG that I can use max. 4/B16 switch, so this is tight space. The efficiency is very good at 94%, but if I want to have 2 more shelves I may not be able to run them all. Are there any other choices?
For 2 of the LM301b strips I could use a 900 mA driver and drive them in parallel, this will give me some mobility as I can put more of these drivers on a switch (I think/hope). With EB Gen2, using PCD-60-700B I can drive 2 in series and won't have to deal with high voltage.
For each shelf I need not more than 16000-17000 lm.
What would you do? Would you take the high-efficiency LM301b over the electricity hogs EB Gen2 (which I could actually drive at 600 mA to consume only 22W for a ~3960 lm output)? The H series do seem a bit expensive but they are a middle of the road solution, as I think I read that they have more chips per strip (72 vs 40 or so), so the light will be less focused and create less shadows.
And the last question is, how and with what would you drive them?
This is a handful, but thanks for anything you might share
