Nah...its all good... there is far worse....this thread, mostly
You are right but I'm saucy today. It is the classic Capt. Picard facepalm.Nah...its all good... there is far worse....
I am color blind and can't see the hidden Where's Waldo facepalm...lol....just see the outline contours...
That retrofit method is not only cheap, it is also convenient and safe, for that floodlight even has IP67 rating. There is nothing to gain with quality chips in this case (well, I guess they will arrive a bit earlier). BTW, my 10W-730 are laid out for 1050 mA, whereas my 10W floodlights have 300mA driver in them. Even after a couple of hours there is no noticable warmth whatsoever, so I am quite confident that this light will last for a very long time.I don't want epistar or a noname led/cob I prefer to pay a little more and have a good warranty and quality!
Have a great day ★
recommend build your own, you can control the spread coverage. 20 mm far red stars are readily available from a number of places. (rapidled, steves led etc.) my builds are 3 foot long 1.5 " heat sink bars with 4 20 mm stars evenly spread.covers a 5 x 2.5 space. building lights with 20mm stars isn't really any different than cob lights, just a lot more tedious since they are so small (not really an issue if you only need a few stars).Im interested in running a lights out far red. Ive read thru this whole thread and what i have gained is ising far red at lights out for 10-15minutes transitions the plants to sleep, saving 2 hours of dark. So i could run 13/11 or 14/10, possibly increase yield? Has anyone continued at 12/12 using far red @ lights out?

Would this light cover a 4x4? Or am i better off building my own light bar out of say oslon ssl80 far reds? I have only ever build my own cob fixtures and dont know much about putting together reds or blues, they appear quite small, do they come on stars?
I think I might build a bar for my tent. If I can shorten my grow while keeping the same yield, use less power then I'm all in. I can build things but I still don't understand how to read what I need.
I live in Europe so of course I am looking at shops close by. I'm in a 80 x 80 tent (2.6 x 2.6)
First the 730nm lights - would 6 be enough or too many/little for my space? These are 0.63w each.

Next is the power/driver. This I still haven't got my head around. I know I want to drive them at 350ma so I am looking for a driver that does that (correct?)
Is this the right one or can I get a different one from the same place?

I'm not understanding what I should be looking for here ... the vmax .. (ok confused here lol) Is it too powerful or not powerful enough and how do I tell?
Nice, Do you think it is better to have 2 drivers cause the last thing I want to do is break it I really hope that this will speed up flowering. My power is bloody expensive (0.46cents a watt). If I could shorten my grow cycle by a week then it is all worth it.Those 6 should cover it mate!
I'd arrange them like the dots on the six side of a die. You feel me? Lol like : : :
The voltage of the 6 leds equal ~11v @350ma
This driver is cheaper and should handle the reds no problem. https://www.led-tech.de/en/LED-Controlling/Constant-Current-Power-Supply/Power-Supply-for-1-3x-1W-LEDs--230V--LT-1087_118_119.html
The driver you linked would not be running very efficiently, because you would be very near the minimum voltage rating. I know the one I linked is rated for 10,5v but putting half a volt extra on there won't hurt
This is all based on theory built from extensive reading, as I have very little real world experience in cannabis cultivation and LED light building.
Take my advice "lightly"
Good Luck!
From Supra's matching driver to cob thread:Nice, Do you think it is better to have 2 drivers cause the last thing I want to do is break it I really hope that this will speed up flowering. My power is bloody expensive (0.46cents a watt). If I could shorten my grow cycle by a week then it is all worth it.
are normal halogen flood bulbs far red?Halogen flood bulbs are cheap........just saying
Yes , incandescent/halogen give off a good amount of fr/irare normal halogen flood bulbs far red?
At 600ma you should get about .6*2.2 watts. Also Far Red are not going to be as bright as regular red.I got two of these:
http://www.mouser.com/ds/2/228/LZ1-00R300-21744.pdf
The problem is that when I hook them up to a 600mA 4-12V driver, one of the leds pulse with a dim light and the other is not responding.
I figured there was something wrong with those leds and ordered two more. However I don't want to test them before I know what went wrong with the first two.
Any thoughts?
