To build on this,
The side effect of blocking some of the wavelengths is that the energy from them has to go somewhere, and if it’s not out of your hand as light then it’s into your hand as heat.
How much heat? No idea. But it’ll be heat none the less.
In a previous post of mine I eluded to this effect. When using a white flashlight the flesh only transmits the red wavelengths, everything else is converted to heat. It got hot enough that I could only hold my hand on it for around 3 seconds.
Conversely, when using a red flashlight, because nearly all of the light is transmitted with very little absorption, I was able to hold my hand on it almost indefinitely.
I suppose though that the difference is my white flashlight was ~3800 lumens, while the implants are significantly less than that
