I’ve been contemplating the DIY red light hats I’ve seen. Some are brilliant, made with artistry and an aesthetic balance that is breathtaking. Some are, um, not so magnificent to behold. Does appearance matter? Not really.
It is not the beauty, it is the function.
If the DIY light hat is heavy, hot, oppressive or worse, covers the face, it is not going to be comfortable to wear, no matter how elegant it looks.
If it is a physical burden to wear the light hat, then it is unreasonable to expect anyone to take on such a daily commitment of misery.
Comfort is the key to any DIY light device.
Here is the List of Nots:
Not covering the face
Not difficult to balance on the head
Not physically awkward or painful to wear for 20-odd minutes at a time
The User of the device must always have the final say.
If the User finds the light hat distressing or uncomfortable wear, the User can and should refuse to use it.
I know that this term has been recently used in conjunction with red lights which is a pity. While it might make a thrilling moment on television, it gives a very inaccurate and misleading picture of how red lights work.

If you follow the guidance given in this blog, you’ll notice that there is occasional mention of heat, because some LED strips can get warm. And anything warm on your head can be uncomfortable.
This is easily avoided by making yourself a light hat that is open and not closed in – the Cossack is the best DIY design.
If you have looked at the availability of rolls of red and near infrared LED lights, you will see that there is a bewildering array, between orangey-red (630nm) to out of the visible spectrum so that you can’t see it at all (940nm).
So what, you ask. Surely it doesn’t matter? Surely red light, near infrared light – it’s all the same? One wavelength is as good as another?
I had a really good question from a blog reader today about why I recommend the Cossack design.
Look at the instructions for DIY light hat devices, and the photos of both devices, and you’ll see that Eliza is all enclosed, with a few holes at the top, and is lined with reflective foil, whereas Cossack is very open, lots of ventilation, no reflective foil. Continue reading “Eliza vs Cossack”
