LED light question

Generally, as long as the current does not pass through your heart, you should be OK, that is why I only work with one hand on hazardous circuits and tube amplifiers. I put my other hand in my pocket.

Then perhaps you can explain why there are thousands of these lights out there and no one has complained of serious injury?

A dead man never complains. I mean come on, this is basic electrical safety. 156v able to push over 2 amp is very dangerous. Really? Do you not know this? The biggest fear of firemen responding to grow house on fire is electrocution. Law enforcement's policy is to turn off the electricity before entering an illegal grow house.

Methinks you're spreading fear and doubt for personal gain.

And you don't even lie well;

Having had law enforcement in my home, I can attest that not only do they not turn off the power, the dumb motherfuckers will even refuse to turn off the lighting while working dangerously close to it!

I think the santa ana police may have adopted that policy after getting caught on tape stealing dispensary goods and talking shit on a crippled patient.lol

NOT TRUE. I would NEVER design a product with voltages over 50V. It is insane to sell a product with a 156v supply and not get it UL approved.



When you have 156V pushing enough electrons through your body cooking your organs and frying your CNS. It takes only 100 mA to kill you. That power supply is capable of pushing over 2 amps. That's just simple, yet very serious, electrical safety. The reason they have UL certifications, so more people don't die.

The resistance of the body varies depending upon the points of contact and the skin condition (moist or dry). For example, the internal resistance from hand to foot is about 500 ohms. 156v (output voltage of HLG 320 C2100) will produce a current of 312mA hand to foot killing then cooking you.

It is true. Votlage doesn't kill. Its no different than a tazer at 50,000 volts.

The 110 or 220 input is more dangerous.

The driver is ul listed.

Quit trying to scare people.

Dude quit.

Seriously. You are talking to people that do this all the time. I have a degree in electronics and used to work with high voltage equipment.

I'm not the least bit concerned. 15y volts at 2 amps does not scare me at all.

I respectfully disagree but I'm not going to clutter up this thread with unrelated pics.

If you're interested I have plenty to show you.

Unless things have changed, I've seen the pics.

What rock have you been living under. If you want to see 10+ top shelf plants grown under LEDs, just open your eyes.

My eyes are open, I said "10'+ plants". LED/COB does not have the penetration for a large scale grow of 10ft tall, or taller, plants. I have ~30 strains that I like to finish at ~5'-8' (strain dependent), but circumstance has sometimes led to much taller plants. LED/COB will not accommodate 5'-8' plants either (from what I've seen).

No shit. I don't need to know how it works. As I just said I have a degree in electronics.

Its true that it only takes a few miliamps to stop your heart but I wouldn't be worried about that driver. The 110 wall outlet is more dangerous.

you said it AFTER i posted that. Sorry, I didn't know you had a big brain,lol

Many electrocutions happen when someone forgets to check if the power is on. I'm sure when high no one would ever forget something.

Sorry, I am not trying to scare anyone. I assumed when I asked the original question that others were aware of the dangers of working around water and electrocution. Ever get your feet wet watering your plants?

Hopefully this will be my last post on this topic.

Yes it is current that kills. These HLG drivers are current driven devices with voltage up to 435v.
The most common I see being recommended is the HLG-320H-C1050 with 300v.

I got this stick figure from a paper, UAW Electrical Safety in the Workplace.

The voltage and resistance determine the current.
While it is current that kills, it does not take very much.

Current = Volts ÷ Resistance
Arm + Leg + Torso = 1,100Ω
100V ÷ 1,100Ω = 90mA

You should have a ground fault outlet for your lights anyways to trip if you do step in water.

I don't respect the ul listing any more. Have you seen the junk that is listed?

I don't work on electric or other dangerous stuff high. I would also expect anyone building a light to know what they are doing.

Other than that the diy light with meanwell drivers and name brand cobs is safer than lets say a mars hydro.


Putting one of those kits together is straight forward and the light wouldn't worry me a bit.

Whatever illumination you used in pics you posted isnt working. Those ratchet 8' poles aren't convincing anyone that your Luddite beliefs are anything but stoner bullshit.

*penetration doesn't mean what you think it does.

I guess my point being when I worked I industrial maintenance I worked with triple phase 440. That's some nasty stuff. It is dangerous to work on. Just to work on it we would have to lock out/ tag out in at least two places before working on it.

I've worked around a lot of dangerous stuff. Flight line work in the military is quite dangerous. There are engines running and blades spinning.

I've had other dangerous jobs and the training with it.

I get there are incompetent people out there.

If a person isn't comfortable building their own light then buy a listed built unit.

This option for people that don't care about ul listing, want to save money and comfortable building the light to have the option.

Here we go again...



How about you post up some of your chicken shit plants so that we can all have a good laugh. Thanks.
