New study: Exposure to LED not good for us

[lukio]

my vpn server

Sup dude. Just a heads up, use Tor on Tails. Vpn' leak data all the time and nobody trying to hide anything should trust them.

@Randomblame
Any idea how are they running 14 strips at 480H48A? is that possible as if so I will add more and get that driver instead? This came off LED Gardner website

That's an example for a parallel circuit using 5 port Wago clamps. You need to do same but with a few strips less. There are more ways to create a parallel circuit. In theory you connect all plus wires together and connect the to the + driver wire and the same you do with the minus wires and the negative output of the driver.

I really like these e3ay connectors below because they are made to create a parallel connections in an easy and fast way. AWG 20 has still enough diameter to not increase the resistance too much, only when you plan to wire the driver remotely you should use something with bigger diamenter.

Yeah, thanks buddy! I know!
My f.... windows machine is down since a while. Have tried to repair it tonight cause I wanted to try the dialux app to work with IES files but seems I need a new motherboard. Currently I use a vpn and the Orbot app(tor for mobiles) but its a really slow combo.
But I hope I have 1 chance left..
The desktop was unplugged from the wall for a long time(min 12 month). Maybe I just need a new bios battery, reset it and it works again? Its plugged in since tonight, so maybe the battery gets charged again but I believe she is deeply discharged and I need a new one. Normally it would only take a few hours to recharge the battery and till now its still dead.
I'm undecided what to do if its not because of the battery.
Repair it(its 10J old at least) or rather get a small laptop?!
How did you use tails? DVD or USB stick? Does it help to use a faster 3.0 stick to increase the browsing speed?
Any recommedations for tails, bro?

what are they called?

Yeah, they are called T-connectors 2 way mid-span AWG 20-22 but that's just the fancy chinese description.
Easier to search by the e3ay part/article number. If you don't find them try e3ay.com and use a browser instead of the e3ay app.

I know exactly what you mean! I always I loved the warmth it gives off.
It creates a somehow homely feeling like the warm white we use at home. If you like it try Blux Vero decor in 2500°k for your living room. I'm using decor series, 2700°k/CRI97 for my living room(Vero10) and I really like it. Digikey has vero10 and 13 in stock the last time I ordered them.




I can't open the digikey link because they block my vpn server but if its a double row f- or H-influx strip (or a single row 4 footer) and has more like 42v but less like 48v then you have the right driver. Simply connect the strips in parallel to still have the same voltage and the driver current is divided evenly by the number of strips connected.
Ah, I remember now! It's q-series, 43,5v at 450mA. An HLG-240H-48A has around 5,5A so with 10 strips each strip gets ~550mA. At this drive current a q-strip maybe needs 44v so multiplied by 5,5A you should have at least 242w net and 255w at the wall, maybe 260.
So, yeah that driver works! There is also no need to change the driver voltage. Better use the current regulator for dimming its far more exactly.
You could use a multimeter to set the driver voltage limit to 45v and add some kind of extra protection. But to reach that voltage at least 5 of the strips have to fail and thats very unlikely.
You could also use the HLG-240H-48B modell. It has no built-in regulators but a set of dimmer wires. You can use a cheap B100k potentiometer from e3ay or the rapidled 6$ dimmer, which is the better solution IMO. Rapidled has maybe a better price for the HLG-drivers too. And with 10 q-strips you are still above 50 bucks so still free shipping/no extra fees.
Believe me you will love the dimming feature because it al!ows you to inspect the plants without switching the light off. The colors will look much brighter than they are under intense LED light. So its really a useful feature!
Dimming also allows you to suspend the light always with the same distance and adjust only the brightness level. With an HLG-240H-48A you are limited to 50-100% dimming and you always need a small screwdriver to adjust brightness.
No "damned, where is this shitty screwdriver again" anymore with B-type drivers. Much more confortable.

I am going the route you suggested with B driver and a pot.
I have A driver unit now and your right it is a pain.
So I don't need a resistor(s) ?
How do I ground it?

Thanks so much for your help again.

I'd definitely try that first, man. Hope you can get it going again but if not, small laptops are pretty reasonable these days.

I run tails from usb...i dont think usb 3.0 would make too much of a difference, if any. I'm away and don't have my laptop with me where I have the necessary info bookmarked but there's probably a tutorial on youtube. Plus i don't remember it being too tricky. Im back next week so hit me up if you need more info. Privacy is a right of ours that's unfortunately stolen at birth...you can get it back though

I liked thses shame wire size on main carrying in isn't a couple gauges heavier wire.
They beat wago's? I guess 3-way or 5 way wago? I was using 18AWG wire into boards and then stranded 14 AWG everywhere I can so if I decide I can make one big light at a time but gee what an idea you not sure now lol

Depends, bro! The driver is grounded already and if you mount it on the backside of your lamp the frame is already grounded properly only make sure they have contact. If you plan to install the driver outside of your tent you can connect a ground wire to the frame and connect the other side to the ground wago you have on the AC input side of the driver.

Resistors are not needed, at least not for the LED's. The driver will anyway switch in constant current mode because the circuit voltage (~44v) is lower like the nominal voltage of the driver(48v). 44v is in the upper area of the CC region(see datasheet) but outside the voltage adjustment range(A type driver). B type drivers are anyway fixed to 48v and if the voltage is lower but inside its CC region(24-48v in this case) they use the CC mode and still deliver their maximum current.
Circuit voltage x max. current = maximum watt! An HLG-240H-48B can have 8% more current so 5,6amps instead of 5,2. So 44v x 5,6A = are 246,4w net and 262w at the wall!

If you use a cheap B100k potentiometer you need to check its resistance with a multimeter. Only when the poti has 108k at least you can be sure to get all the available drive current. If your poti has only 98k you need to add a 10k resistor to the middle prong otherwise you're limited to 98% of it output. These potis can have between 90 and 110k and in a bunch of 10 you'll maybe find one with 108-110k.
The 6$ rapidled dimmer works with 0/1-10v but does not need an extra voltage source because it converts the 100μA of the dimming circuit it something it can use. Its minimal bigger but of far better quality, comes pre wired and is a much more elegant dimming solution cause it can always use the full driver power and you need to check nothing before usage.

Yeah, to install it on a stick is pretty simple. You only need an installer tool to install it on its own bootable partition on the stick. You r right, here are how-to's on youtube also especially for tails.

The reason I ask is, tails doesn't run on the build in HDD/SSD it uses only RAM and MB of the pc and the build in SD/MMC card storage of the stick.
High IO operations help to speed up the tails(linux) UI and browsing experience in the same way like an SSD speeds up your windows or mac UI. So a fast USB 3.0 stick made to work with high work loads (many small files, high I/Ops) should be the best option. I mean not a fast transfer rate, that would be easy to find, but one who executes long rows of input and output operations the fastest that's not so easy to find.
I've just hoped you would use something like that already. Photographers often used SD/MMC cards with the same features to make sure high resolution photos and videos can be stored fast enough to cause no data loss.
You know like it is, bro. Hope dies last, lol!

Shit with cheap laptops is they have slow transfer rates even over USB 3.0 and with the card readers its the same. I remember when I've used my old stick to browse the darknet .. it was always a pita.
Hope I get it fixed with a new battery.

Newer study: exposure to sunlight not generally good for us either.

Honestly, you shouldn't stare at any light source for an extended time...Unless you want to win a Darwin award this year? lol

Sit in a dark sheltered room your whole life to keep your eyes truly safe.....I'm not.

and for the love of god don't breath o2 or eat anything because its all bad for you...

New study today.. Eating fruit is as bad for you as drinking pop..

one last question
I have 14 strips coming not 12 , they had not shipped so I added to it
Will drivers in diagram will work as it seems way to powerful for 14 strips @ about 20 watts I figured ?
is that correct ,please excuse my redundancy
I think it should be a HLG-240H-48B same as was, just run em cooler, there is no limit to how many i can connect together is there?



Also they will be the 5000k spectrum same strips though

Yeah for sure know what you mean, the cards I use for work are CF cards and uber fast for writing data like you say. But I seem to vaguely remember a tor dev (or someone similar) saying on reddit (also a great place for info at /tails and /tor) it wouldn't really matter...i think it's all designed to be light weighf for ease of use. I'm probably using a 3.0 but not entirely sure?! Lol. I'll check when I'm back, travelling with tails on usb raises suspicions I'd rather not deal with travelling around asia

Ah ye old darknet...troubled times at the mo for the markets. They're being held to ransom by a hacker that's found an exploit Tor side that makes it real easy and cheap to ddos the markets. He's trying to extort them. Tor need to fix it...theyve apparently received some very large anonymous donations....lolll i wonder why haha.

Ah, okay! When it makes no difference I don't need to search further. There is probably also a new tails version available ..
If I get the issues fixed I'll install the latest version on a few sticks I have laying around.

Lol, yeah! I've read something that they have closed another market place not too long ago and that they have found a way to identify the servers easier. Maybe with the same hack...?!
Hopefully the tor guys can fix it soon.

It doesn't matters how much strips you connect in parallel, the voltage still stays the same (almost). 12 or 14 strips in parallel means maybe 0,1v less circuit voltage because driver current divided by 14 means less current per strip and therefor slightly lower voltage. But in the end it works the same and with more strips you get slightly higher efficiency. So you have still to use the same 48v driver.
Maximum of the q-series is 900mA so with 14 strips the maximum is 12,6amps for this parallel configuration. You could use an HLG-600H-48B(12,5A) and you would still stay around the maximum rating. And you could still use your desired heat sinks, q-sieres has anyway wider diode spacings. Add one more strip and you're for sure below 900mA even if the driver has 13A in reality.
But I would rather have mixed 5k and 3k, they all have the same voltage.

I have two -HGL 320 X'sL with 3000K V-2 boards already hence my choice.
Now these in 5000K plus I have a HGL 4000K veg light, two T-8's with two -32 watt lights (64 watt total each light) 2 bulbs each UVB solocure for total another 128 watts which I tested half ass and really like so far, they bring out smells and colors you were right.
I will get two more strips when I order driver once I price it out for total of 16.
Once I figure how I blocked my cell from linking to my pc I will post pics I have a firewall.
I think I am starting to understand how drivers work at least a little!

thanks for your help again dude!
You should teach this stuff.

Yeah, make sure you remove the meta data of the pictures or just make screenshots of the pics you want to upload.
A firewall protects you from spyware but it doesn't help you to stay anonym because you still use the same IP.
A VPN can only mask your IP and change it in a different one but TOR(the onion router) changes the IP a few times by using several servers within the tor network so that its almost impossible to identify someone.
Tails + Tor alone should be enough but its also not completely impossible.

There are a few tricks like using a fake email adress to create an account that will help you to stay anonym but most important is to change your IP. As Lukio's has mentioned, a VPN alone is not 100% safe. Its better than nothing but if someone tags you in realtime they can find you easier like with tor.
So in this point Tails/Tor is already safer.

 

[lukio]

@Randomblame yeah dude, they seized wallst market. They arrested 3 admins in Germany after one of them used a vpn + tor, the vpn leaked the server ip and from that moment on they were screwed. Their general opsec, ignorance and stupidity was truly mind baffling. I've read the official affidavit and it's ridiculous. Funny thing is the admins were mid exit scam with ~15m dollars worth of vendors bitcoin so its a nice bit of karma. Their days are numbered for sure.

Tor is extremely secure if you follow the rules but theres been some recent improvements with something called deep-fingerprinting, that's lil worrying.

It's a constant game of cat and mouse that tor devs have been winning....

and its nothing to do with led lighting aha!

- Wear shades in the garden. Blue light filters on most phones these days say it all.

 

[Glovelove]

Do they make led specific grow room glasses like they do for hps lights? I have some method 7 knockoffs and they work great for seeing the actual colors of the plant when you're in a bright grow room.
