Just before i e-mail you the response i got i am just wondering what your lenses were cleaned with before hand ? this is a serious question and not any finger pointing but we had an issue with certain cleaners and traffic film removers doing this to certain cars and certain headlamps : Nissan notes were one of the big issues we had it with as the headlamps were fitted in perfect condition then when they had come back from the wash and the valet bay we had issues,which took some investigational work until we finally figured out what the issue was and that one in question was the film remover not been mixed correct so maybe was too strong acidic or something who knows ?
but as i said the reply :
Hi many thanks for your email and custom...
We have supplied our light protection film to the motorsport industry, namely Lemans for very nearly twenty years.
During development we had to manufacture a product to meet the strict demands of racing organisations and race teams around the world as far as impact protection, grave tear, breathability/settling specifications, weights and thicknesses, shrinkage, colour and light output color, UV degradation, adhesive longevity and thermodynamic properties such as heat dissipation, melting points and much more.
It's disappointing to see incorrect, unfounded information and defamatory remarks regards our product, especially when compared to a simple (Perforated or cross cut) signwriting graphics
vinyl despite
the fancy names. Our product is completely different and we would never recommend anyone, whether within the motorsport industry or not to use a graphics vinyl on any vehicle lighting...We can but only advise as far as this .
Regards heat, our product will actually show you how well it dissipates as it will feel hot to the touch when compared to a lamp without having had our product fitted. This is through effective heat soak and dissipation, our product draws heat into it from within the lamp unit/lens and actually allows a cooler operating temperature inside the lamp unit as heat is then dispelled into the atmosphere. (Thermodynamic transfer/convection/entropy)
Even though there is actually a small offset due to the 'barrier' effect of the product. This offset is greatly over compensated for and it simply has to be to allow us to supply the industry.
A relatively simple explanation is to imagine a piece of copper (Extremely effective), perfectly sized and shaped to match your current headlight lens, if this copper is placed over your existing headlight it will feel extremely hot compared to the original lens alone, but as the transfer of your original lens is now increased, so is the effective heat dissipation. Again with a small increase in temperature due to a barrier effect but once again overly compensated for by the area and effective heat dissipation. We use copper as an example here as it is very effective for heat soak and also heat dissipation, our product (Which is breathable for adhesive curing and thermo properties) works in very much the same way.
This is actually all very complicated stuff, and I have missed out many factors such as density differences, outside temperatures, interior volumes, exterior forces (cooling).
I hope this helps , if you did feel the need to return the product then we are of course happy to discuss this with you, and we treat any returns/exchanges with the same priority as any outright sales through our relatively recent website, which caters for sales to the general public.
Many thanks,
