How to buy the right red-light device

@Luke What do you think of this bad boy?
-
@Luke pretty sure thats the one I have too and it's awesome, I've dropped it a bunch of times and it is fine.
-
@sunsunsun What improvements do you notice about it?
-
@heyman I use it sometimes for muscle soreness , other inflammations etc and it knocks it out fast
in winter shining it on neck / thyroid for 3-5 min is decent replacement for daily intense sunlight
sometimes when working at desk I prop it on desk to the side so it indirectly shines in eyes, seem like it is good for eye strain prevention
at halloween it makes nice creepy light

@sunsunsun What difference is it from an incandescent 250w bulb?
-
@heyman it’s red

Sunlight contains red light and a whole lot more.
The sunlight spectrum extends far into the infrared range and it is the infrared portion of the spectrum that produces heat. Incandescent light also contains portions of the infrared spectrum but it has much less blue light.
As far as I know, all LEDs contain a large amount of blue. The people who sell red LEDs cleverly neglect to show you the blue portion of the spectrum so you are left in the dark about the amount blue they emit.
Dr. Peat liked incandescent light. He liked the spectrum produced from running 130 volt incandescent bulbs in a 120 volt system. That is what influenced me to purchase this pool light in 2016. It is still buring brightly today.

I was not certain if the 130v bulb would be throwing off enough heat to melt a plastic socket. So I got a unit similar to this one with a ceramic socket.

@DavidPS Interesting, don't think 130 volt would work here in europe though.
When I asked ray about light he always recommended the incandescent lights. Don't know if it was his thing with keeping it low cost (keep it real yo) or disdain towards led lights. When I asked red light man he said incandescent light bulbs are very inefficient, producing mostly heat.

I'm guessing they mean 130W bulbs. As in watts, not in voltage. The stronger incandescent bulbs have a nicer spectrum closer to daylight in comparison to the low wattage ones which tend to be very yellowish and lacking contrast. The picture above looks more like sunlight spectrum through window glass and not quite right for an incandescent spectrum as there would be much more "wasted" energy in the IR part beyond 800nm. Which makes incandescent uncomfortable at close range unless it's very evenly spread as it comprises the peak frequencies for heating up tissue water. Maybe the graph's curve is a due to a restricted spectrum range of the measuring equipment.

@CrumblingCookie In this 1-minute clip Dr. Peat explains that running a 130 volt bulb in the standard 120 volt circuit ('standard' in the US) results in a weaker blue emision.

@DavidPS Thanks for your clarification. Vaguely remembering this one now.
I've never tried them side by side. Wondering whether the lower blue light emission of an underpowered 130 Volts bulb in a 120 Volts socket compared to a 120 Volts bulb in a 120 Volts socket is any near to using a weaker (less wattage, therefore "warmer" color spectrum) 120 Volts bulb. Have you ever compared and noticed the differences? -
@CrumblingCookie - I have not made the comparison but it is a good idea, Haidut started a thread about this back in 2013. I have not reread the thread; I have already made my purchase.
