PSA Too much light

Like Dano,said about the 315cmh i like my new light but i can't see it being as good as a 600hps, like the manufacturers said it was, maybe close to a 400hps at best.
 
Hey MarkyJ, You can bet these grow lights ain't good for you ,especially for any length of time, an especially if you already got damaged skin from swimming an sh-t over the years. I'd sure use caution. Merry Christmas
 
I think if you can get in there after lights out or before lights on you'll be fine a green head lamp or a green bulb will do the trick just beware of light leaks from the outside area of your grow space when you go in.
 
Alright, I was confused after I read the LED article (which turns out to be Loony Tunes) so I reached out to
Brendan Strath Senior Solutions Director & Grow Ninja @ Spectrum King LED. Brendan sent me a detailed email on the subject of MH/HID light dangers and I am happy to share it here. The major problem is ecological not physical danger although in the case of the envelope (some have a double envelope) breaking and a flair up eye sight can be affected Some have said they experienced temporary loss of eyesight. Here is the detailed email I think the links will work.

Paracelsus,

They are not being banned for their poor spectral output but because they contain toxic waste. Unsafe heavy metals are polluting landfills all over the world and leaching into the water table. A scary amount is directly linked to improper disposal of HPS & MH bulbs.


Colorado notified all growing facilities in their state with the following letter:

The federal government has banned many bulbs and wasteful, toxic HPS and MH are closer to extinction than ever before. Basically inefficient light sources are being targeted and over time more of them are being banned. When this ban was signed:

Also many bulb manufacturers had to change their manufacturing processes to make more efficient bulbs which was written about here:

The aforementioned are just a taste of the "gov't speak" which show clearly that efficiency and waste are on the agenda to be dealt with. The wattages for banned bulbs started smaller (ie 40-60-100w incandescent bulbs) and are now working their way up to 1,000w.

The spectral dangers of UV and IR emissions are real as well and being discussed at the government level. Basically you should never stare or look into any bright light source but some people have and then want to blame someone else for that stupidity. That gets politicians talking and we'll see what they come up with, if anything pertinent. The real issue is the toxic waste but the inefficiency is a close second as a large portion of power is wasted by HPS & MH light sources and as our country looks to become more energy independent all things inefficient are getting scrutinized.

This factoid excerpt from a large article puts it best,"Although e-waste accounts for only 1 to 4 percent of municipal waste, it may be responsible for as much as 70 percent of the heavy metals in landfills, including 40 percent of all lead." That is an alarming truth and means we as a people have been polluting with toxic waste and polluting water tables for over a century. Not good for us now and definitely not good for future generations.

The Roman Empire most likely fell due to using lead pipes for their water supplies. Look that up if you get a chance. People went sterile, crazy, birth defects went way up and over time that lead to the end of their way of life. It wasn't war (although they had plenty of that) or most things we think of but lead poisoning and we've been doing that to ourselves here and now.

Let me know if you have any other questions.
Thank you, Brendan Strath

Good share, just to be clear the UV emission dangers is related to metal halide only. Also i fail to see infrared dangers. We have infrared heaters all over the world, any issues with IR with lights would be just the same as infrared heaters. Which are used all over the world for commercial purposes.
 
I've been battling skin cancer for 15 years, stage 2 stage 3 melanoma is on my back and arms, didn't get it cause by the moonlight. Most of my damage came as a young kid being in the Florida Sun with pale white skin, well it used to be pale white till the sun burnt it. Basically the dermatologist told me I was allergic to the Sun I guess that mean lights that put off any sort of radiation and or UV ... ☮️
 
Genetic predisposition to malignant skin cancers. I am on a immunosuppressant which practically does the same thing. So i cannot be out in the sun for too long or i increase my chances of developing melanoma.

Best of luck to you.
