Hi Led is equal to about 2X the HPS wattage, so 300 watts of leds (at the leds not the mains) is equal to a 600 watt HPS. This light will be equal to about 160 watts of HPS. One thing to consider is the heat - 160 watts of HPS puts out 40 watts of light and 120 watts of heat (25% conversion of electricity to light) but this light puts out 40 watts of light and 40 watts of heat (50% conversion of electricity to light). This makes a big difference, especially in summer.... Part 2 coming this week....
8:20 the other way around and it would have been true. Don't put a 100 watt light on a 40 watt power supply, it won't work that well, in fact it'll most likely eventually blow a fuse inside the power supply. But there is absolutely nothing wrong with putting a 40 watt light on a 100 watt power supply, so long as it is the correct voltage. So, best to get a power supply that can deliver more wattage and current than you're actually going to draw.
@@fish9468 it depends. Some fancy power supplies have some smart switching or relay mechanism which protects against drawing too much current, but by far most power supplies that i've ever looked at inside simply come with a fuse that will blow when you attempt to draw more current from the power supply than what it was designed for. Regarding efficiency I believe most power supplies are at their most efficient when operating at about 80% the load they were designed for. But this will probably vary with different power supplies, so best to check the datasheet with the specific power supply you're dealing with.
@@mortenrobinson this is an led power supply. Most are CC, and the CV ones are never dumb enough to have a fuse. We’re not living with ww2 electronics anymore mate.
It's never really going to be much fun until we can buy blank aluminium substrate PCBs and make our own boards. It seems really hard to find anyone willing to sell blank boards. I guess it's difficult to etch around the copper traces without eating through the insulating layer. I'm not sure how they're made. Then again... I don't think it would be a deal breaker to just use a regular blank board that's as thin as possible, and just mount that on a heatsink or sheet of aluminium or copper. It's not the best thermal interface, but then nothing with a high electrical resitance is going to have great thermal conductivity. Hell, I'm sure the LEDs would be fine on a regular board as long as they're not being pushed close to burning up. Just use more and don't push them as hard, maybe
Brilliant! I'm heading to part 2 now. I'm a little confused by your accent. You state things in pounds, which I understand, but you say aloo-minum instead of aluminium. Whatever. Thank you!
Good tutorial ! Maybe I'll do it. What are the equivalents compared to a HPS? I'm waiting for part 2. Thanks for sharing

Sorry for the delay - the video is up. The final part will go up tomorrow - it wound up being 40 minutes so I split it in half.
@@plantphotonics6348 thanksyou !
you even did it in pounds youre a sick guy
He's a legend.
What happened to plant photonics? Why do i get redirected to lumatec when i try to load the website ?

Nope. It’ll just run more efficiently. No blown fuses

Fck you both, just confusing me. I won't listen to any of you.

what is the ratio of each color
Only 70-80watts in 60x60?? Im using 780watts during flower
centimeters im sure lol
What’s with the bracelet?

Sounds like he’s English trying to put on an American accent 😂😂
For that price I'll just buy a little light
They're light emitting diodes : L.E.D.'s not "leads" (ledz)
