Yes and don't sleep without a smoke alarmHa my cheap LED are LM281b+ diodes $50 work well see them in my other posts. I'll have another 4 here tomorrow

Yeah they work, but if you were to compare watts per usable light produced a good diy light will produce the same amount of light those lm281b chips from 10 years ago will produce using half the power. So after 2 grows your extra power burned cancels out the extra money spent up front, not to mention the multiple ounces produced because those Lm281b can't penetrate as far in the canopy. Also the diodes used on cheap Chinese lights yes they are samsung but they are the lowest binned. Bin is the category they are in they may be the same diodes by name as HLG started out using but they are the lowest binned which means the are not as efficient as the higher binned chips. So the cheeky little fuckers use the name to suck you in making you think you are getting the same diodes but your not. When they die you can swap out the boards for good ones and have a killer light for nix. 2 of my diy lights @ 300 watt each is way to much for a 4×4 if turned up full and bleaches the fuck out of the tops I'd have to run C02 to be able to turn them up at a cost at less than 400 you'd need a 600w HlG R spec to even come close at 3 times the priceHa my cheap LED are LM281b+ diodes $50 work well see them in my other posts.

@Green Genius Any chance that you could expand on the HLG thing posted on Insta? For some reason I cant view it.
As for on the topic of burn out with the diodes. That was the defining reason i bought an oversized light than what i needed. Running a 1k driver at 60-65% powering 10 full spectrum bar lights in a 1.5m tent, I'm getting the maximum DLI figures each day. If I push it anymore bleaching and foxtailing kicks in.
So yeah, in theory running at 60-65%. I should be able to extend the life of the driver and diodes. Three grows down with it now, I've consistently pulled 1.2gpw or better. If/when it ever gets down to 1gpw grows, I guess I'll start looking at a new light. That's if it doesn't shit itself in the meantime though.

If you go through the threads you'll find a confession from someone who used to stick the wheel on the old style meters with a skewer and blue tack. Then the panic on wich was had when they came and swapped it out thinking they would bust himAh WTF! I heard you can get your power for free if you know how to play around in your roofs wiring make your own earth and by pass the digital meter. I wouldn't know how to do that though

It's footage of a warehouse grow full of HLG with nearly every light has panels with LED out, some have atleast half the leds out.
I also Run lights to big for my space at about 75%. But being DIY i can get parts when stuff burns out. Or like with my strip lights just replace all the strips every so often for around 150 bucks for 10 × 1100mm strips

I ventured down this route as an experiment with a 240w kit for a small veg cabinet. I got 2x 120w QB knock-offs with heatsinks, and what looks to be a genuine mean well driver. It turned out alright, but it's done very limited hours.
But yeah, there's not much of a saving to be had. If I was to do it again. I'd buy the driver off Ali Express, but I'd source the panels locally in Oz like a few do here already.

Finally got it open. That's fuckin' terrible, lol.
Here's me copping shit for buying a spiderfarmer light by folks that bought and praised HLG lights. Too funny..

Yeah trick is to learn how to pair drivers to boards strips etc and be on the lookout for shed lights etc that have drivers that are big enough to use. You can make very good lights for very cheap

that's why you bypass the meter entirely. power at roof before meter, safety switch, bunnings and your own earth rod in the ground, so I heard..If you go through the threads you'll find a confession from someone who used to stick the wheel on the old style meters with a skewer and blue tack.

with the old meters I even seen car jumper leads used

I’ve been thinking about solar on my shed, but first quote scared me off. $13k for a 13.2kw system. I thought they had come down in price. ..

Depends on the rebate situation? Been a few years since I handled a install, they were trading some carbon credit thingos and depending on the market price, meant different rebate - got lucky at the time before a market crash. That was around $6k for a 5kw system. 13.2 is pretty big, I'd reckon 10k would be a fair starting point depending on components. I'm out of the loop tech wise, but also depending on exchange rates since all the gear is imported, and labour costs are always going up

We got quoted around 8 for a 9kw. Running my pool and hydro bring the bill up from around 600 to 1200 and over 1500 when we have the aircon blasting in summer. So I figure if I can get the solar to take care of the hydro and pool it will pay for itself in about 4 years. Not to mention i could make a nice controlled room out of insulated panels with C02 like i used to have in Sydney before power went through the roof, and massively increase yield
