~imagine the node spacing on a plant with a 25000K 250W MH over it. A normal 3 foot plant would have 1000 nodes, LOL

Thanks Scrub for the numbers, I can work with those. I'll just get out my meter see what I come with. It should be easy to figure out once I see what the usages are. Thanks again my friend, I'll let you know what I find.Ghost, that is a great question! Phew! I've never done it, but here's my suggestion: First inspect the unit to try to see if it lists it's voltage or power needs. If no luck, inspect how the batteries fit in. For instance, I think an AA battery is 1.5v. So if one led unit takes 3 x AA batteries, and the batteries are connected in parallel, then the unit needs a 1.5v power supply. If the 3 batteries are connected in series, it would need a 4.5v power supply.
So hopefully that allows you to work it out? If one LED unit takes 1.5v then you would need 8 of them wired up in series to match your (presumably) 12v supply. Wiring in series would be a poor choice though. It would be better to run a 1.5v adapter and wire as many as you need in parallel.
Hopefully that's all correct, that's how I'd do it anyway. No idea how you would ascertain the amperage needed though. Probably run it on batteries first and use a multimeter or something. Also, you would probably want a regulated supply for something like LEDs....not really sure. But voltage can vary on some designs of adapters. You know how some wall-warts are heavy as shit, and some are very light? Well that's part of it.
In case it's not obvious, you would hook the wires to the battery terminals, assuming they have no direct input jack.
Okay! It finally got through. Miracles all up in this bitch Day 18
Leda Uno:
10,000k doing it's thing! Like I said it's the stretchiest plant I've ever seen but the nodes seem super tight compared to the PK. I should have had all the bulbs in right through the first few weeks for the PK. Ah well. The 4th light did have a good impact on stopping the PK stretch for the one night it's been in. Temps are fine - top of cab temp is like 78º right now.
PK scrog:
I flipped the orientation so the front is now the back so the other side gets a little 10k love. Soon I'll probably put the 10k in the centre of the 3 bulbs over the scrog.
No worries man. I edited that post for a long time before posting so it wasn't like, too bitchy, lol. It's just that in the last few days, I've been told:
- my kelvins are wrong
- my bulb placement is wrong
- h2o2 in coco is wrong
- coco can't be overwatered
- and plenty more.
Getting sick of it, just so you all know. Hopefully you guys see why I'm frustrated. Peace.
