I will look out for those 2 mate. Ive looked on the one i bought which was suggested by some good person on here, but nowhere can i find where it tells you any such information

Check this one out before it's totally sold out. I just built a 260W kit last night and went to order another, but they're sold out already. They still have 135's though, and I just ordered 2 of those. Awesome deal for HLG if you ask me. And use coupon code "DIY10" for 10% off. $232.20 for 2 shipped.

Nice one @coreywebster , and thank you. So when looking out for a decent LED what sort would you be looking out for, if the 1000 and 2000 etc dont get near that, would i look out for a 600Watt one? And then how would i know much exactly i would be getting out of that.
Youve done a great post, but you are way to advanced than me, and i think you must of thought you were talking to someone well advanced lol. This is the first grow and even my first look into may adding a bit more light mate. Sorry if i sound a right thicko but im trying take so many different things in my head is cabbaged :D:D

Pretty much every light on amazon that is blurple will use the same tactics so for cheap LEDs you need to read the small print and aim for 50w per square foot.

Some good LED companies to look out for are
Horticultural lighting group
Timber grow lights
BcBlondes
Growlights Australia
Cutter.au (solskin)
Diyleduk sell a range of quality lights.
Cobkits sells parts to make cob lights.

The best way to get a good LED for a lot less coin is to build your own but obviously that sounds daunting to a newb, it did to all of us too but its not difficult and there is plenty of people on here who will help.

Look for white lights that publish their umol/joule info, give proper par maps(light intensity in different places over a given space)
With top quality LEDs we can run around 30w per square foot.

Maybe start by looking for lights that use Samsung 301b or h diodes, though there are plenty of other top end LEDs that use other equally good didoes, the samsungs are the top sellers currently.

Is that code correct? I thought it was riu10 for 10%

Thank you so much for going to so much trouble mate. i get what you are saying, its just down to me to work out how to actually read and work out how much they are giving out. Really appreciate all the trouble you have gone to mate

A picture of any info actually printed or stuck on the light, a web link to the light or even the name and model of the light would normally be enough for somebody on here to tell you the actual draw of it.

As you can probably tell already, most people on the forum are happy to help out if they can, and there are a lot of people here who are shit hot at electrical stuff.

srry lol yea a plug in is 220vlt in total or 110vlts per socket usuualy two thats why they are 220 vlt. thats how fast the electeicity moves through the light system all things plug in are 110vlts unless if its an adapter like cell phone charger that converts it to 9vlts. amp is how much power it takes to run or move something the heavier the push like a starter motor the higher amps. the lower the push like lights the lower the amps most run at usually min 0.8 amps or higher.
so now you take 110x0.8=88 thats true actual wattage. when i harvest i a get yields closer to my true wattage rather than the lights supposed wattage which is 1000wtts

and on a vltage meter dcv is vltage reading and dca is amps dc os direct current use this because this is electricity value in one direction and ac its mixed value cause the current can change directios but thats irrelavent to the topic lol u just wanna use dc

I've been looking into led lights lots recently as got a Phlizon 600w to find out it was garbage. I am a complete noob to all this but have done a lot of reading so thought I would share. If my information is off somewhat I'm sure someone will correct me.

30W/square foot(actual power draw) is a good rule of thumb, but then there are lights that have more efficient led's that will give off the same light. Don't look at the wattage in the product name as it is sooooo misleading.

My Phlizon pulls 115W from the wall but states its a 600W and gives a PPFD value of 900umol at 6 inches and PPFD of 350 at 18 inches. Where it gives a good amount of light for flower at 6 inches from canopy it has a very small footprint requiring more lights.

To compare the Viparspectra 450W actually draws a stated power of 200W with a PPFD of 2500umol at 6 inches and 619 at 18 inches. So somewhere between 12 and 18 inches for good flowering light as 12 inch PPFD is about 1100. From these figures i would be inclined to go with the Viparspectra.

Looking at a third and what I may be inclined to go with if I had a bit more cash and hadn't wasted money buying crappy starting gear.
The platinum LED P150 draws 90W and has a PPFD at 6 inch of 1800, 12 inch of 920 and 18 inch 545umol. Where the numbers look better in the Viparspectra concerning PPFD, the Platinum LED is double as efficient. Also looking back to compare with the Phlizon, it has a lower power draw with a substantially better light output. The Platinum is also double the price of both these lights but then if you plan to be running them for a long time then you should get back cost in money saved on electricity.

The figures used are all from sources apart from power draw of the Phlizon as I had a wattage meter all ready.

These are all blurple lights however and light spectrum has alot to do with things aswell which I'm trying to understand more myself.

Hope this helps and please correct me if I'm wrong.

I would take those par numbers with a pinch of slat to be honest.

Learning about spectrum is difficult because these cheap light companies use really old data based on single diode colours and not really relating to cannabis or anything that useful.
Bets to watch any vids or read any papers by bruce bugbee , but even he doesn't have all the answers because nobody really knows yet.

The only thing we do know is quantity seems to win over quality, meaning more photons outdoes spectrum

I would hope that at least the figures from platinum lights and the 18 inch figure for the viparspectra are good as got them from a comparison video where the guy was using pretty legit looking equipment. The video gave round a bout the same figure on the viparspectra as the 18 inch figure you get in the product specs. The phlizon is anybodys guess but i have mine at 12 inches away from seedlings with no issue so could definitely be weaker than described.

Yeah i just got round to watching videos as realised I may be able to see guys physically measuring outputs rather than just going with what some one has written down, as a lot of the "best led lights of 2019" etc seem to be filled up with what I had ruled out as crap, so maybe getting paid to say good things about it. That being said you get videos like that also but if nobody is measuring anything then best to take with a pinch of salt.

Thanks for turning me onto that guy, got into other videos by different experts also. Don't know if it has made it easier or harder to choose a light now haha

This is what i used for flowering. So anyone who isn't all familiar should not just mis-spread false info about LED's. Not trying to pursue anyone to buy LED's or not trying to prove a point here. All that glitters is not Gold.
