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.

Im a fan of polarized raybans :cool:

Not sure if there are specific glasses.

And I actually bought the original green method 7 shades....whatttaaaa rip off lol! Real handy though

@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.

Yeah, as soon as they have you on their radar it's only a matter of time. Problem with VPN's they are legal companies and depending on the locale laws they have to work with them in the worst case they call you drug terrorist, lol!
I even believe they have used a german VPN service instead on in bantuland or elsewhere.
I've decided to order a small lappy no matter if I get my desktop back running and go stricly with tails...
Have a bit pa- pa- paranoyer now..

why exactly would these be useful in a WHITE light environment?
Click to expand...
You have probably already recognized that plants look much brighter under white LED light. Especially under lower CRI's. When I switch my lights off they look much different and much much greener.
But I don't believe green sunglases will help here in the same way they do with blurple light, where green is the most missing wavelength. Green glases elimate the blurple tint because they add green to blue and red.
For white light that's not so easy cuz we maybe need sunglases that fill up the cyan range to see true colors. That's the most missing wavelength in white LED light and should have an according effect. The color of the glasses must add what is missing so that the eye perceives the natural colors.
I've not tried it but I believe sunglases in this color exsist already. RayBan has such a bright blueish green tint I believe. Maybe a polarization helps too but normally polarized light looks even brighter. But maybe a combo would make the effect even stronger?
Has anyone blueish green(cyan) sunglases here to just try it out?


Edit.
That's one I've found on e3ay. Polarized sunglases in blue-green / turquoise .. 12$. I've ordered one to try it, lets see if it will help or not.

@sethimus I quoted the wrong comment. Soz
The blues from computer screens and mobile phones cause damage...ive suffered this from editing my whole life. Id recommend looking after the one and only set of eyes you'll have.

I use polizarized filters at work to darken skies and reduce glare and remove/ad reflection on water. Depends which angle you hold them. My eyes are photosensitive these days and it sucks. I blame blue light

you could start by stating which colors are over represented in WHITE light and which you want to filter out. how about that?

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.. :wall:
Click to expand...
The New study was on drinking fruit juice not eating whole fruits. To say eating whole fruits is bad is to throw a super food under the bus. If fact experts say if there was one thing people on the planet could do to stave off a premature death, it would be to eat whole fruits and veggies every day. If you dive into the science of it we need the pulp and fiber to help regulate the sugar so eating the fruit is simply not the same as drinking the juice. link to the study https://jamanetwork.com/journals/jamanetworkopen/fullarticle/2733417

I just use my polarized fishing shades.
Click to expand...
Me too
Good value and excellent optics, UVA and UVB are a must with all grow lights.
Worried about eye strain and/or damage, try going out water for 12 hour in summer sun on a big water ,no shore for miles , just flat water.
I find grow company sun glasses a ripoff personally.

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.

@Randomblame
just confirming model of strip that I have 14 of coming it is the
SI-B8R201B20US
LED MODULE LT-QB22A
5000K STRIP
450mA
Flux @ Current/Temperature - Test 4000lm (Typ)

Going to order meanwell driver tonight the 600H-48B
Also you mentioned the connectors
do i get the two wire of one wire?
16 strips get how many packs 3?

https://www.amazon.ca/Wire-Connectors-Universal-Wire-Stripping-Connector/dp/B07F3Y7YNF?th=1

Heatsinks 1100 mm by 20 mm (strip is 18 mm wide)are my other issue anyone has cheap supplier online?
Strips should have tomorrow
Just need to pick up so bigger wago the 5 point ones should I get 1/2 dozen or so to make light? I have lots of the two port wagos though already.
I should get at my other light I am working on to finish it
thanks for your help

Heatsinkusa is a cheap online shop for heat sinks.
Yepp, that's the 4ft Q-series strip, 43,2v @450mA and probably 46-47v @900mA. Which type of connector you use depende how you wire them. If you add all + wires on one side and all - wires on the other side of the strips you can use the single type connectors. But you need twice as much connectors when you do it this way. I would just use the 2 way connectors and use only one side of the strips to build up the circuit.
In short...
Connect the outer strips (the 1st in a row of 7in parallel) on each end of the fixture directly to the driver outputs. The HLG-600 has 2 sets of output wires, you can connect 7 strips on each side.
When you have + and - connected to the drivers you just need to add these connectors to each of the other 6 strips on each side and then you can add them to the same wires you have used from the 1st strips going to the driver. Put some fabric between the connector and the pliers when you press them together. Not that you damage them.

I mean just like this..

Oh and thanks for solacure idea, Dennis sent an extra bulb so have 5 bulbs(ordered 4) to use if I wanted.
Well made.
odd color it emits but it sure works.
