You could post the picture, but I won't need it. Really don't worry, I have never bought or used them, I will never use them and I have no reason to even think about doing so.
I know that using coils causes e.g. blindness, bulging eyes, MBD, burns... in addition to not wanting to eat, hiding... and it saddens me always so much seeing those poor beings suffering (at least, when they are appearing here, this means they likely get help).
Animal health and proper husbandry mean a lot to me, for my dragon and for other pets I had in the last decades (was always looking up tons of information before getting any kind of pet, and never did the "simple PetSmart kit" setup).
I was just asking for technical information (such as: this type of coil has this spectrum with lack of..../too much... intensity at this or that wavelength, causing this or that in the metabolism, inferring with those cells...) as I'm very much into that because of my job as a researcher, and if you don't have any, no problem
