Mirror Film Visible Light Transmittance Question

CupMan

Hi,

I am looking to use mirror film for my magic mirror. I’ve read a couple threads here and elsewhere and know that it is not ideal but does work. Unfortunately I cannot find a reasonable priced two way mirror in Canada :(.

I am wondering if anyone knows what VLT I want? The mirror film I have found on ebay ranges from 15%, 20%, 70% Visible Light Transmittance. Anyone know what would be suitable?

I am currently looking at this one specifically: http://www.ebay.com/itm/One-Way-Mirrored-Window-Film-Solar-Reflective-Silver-Layer-Tint-Wide-39-37/152611031512?_trkparms=aid%3D555019%26algo%3DPL.BANDIT%26ao%3D1%26asc%3D46673%26meid%3D5b545dca9a1e4c10b4a627cdd3e8addf%26pid%3D100753%26rk%3D1%26rkt%3D1%26&_trksid=p2045573.c100753.m4841

Thanks,

Visible Light Transmission or just light transmission, whatever they want to call it is basically how much of the light it lets through from the other side.

with films you should also find the light reflection number, this will indicate if it would actually work as a mirror or just a shiny metal pot with somewhat of a reflection in it…

Anyhow, the higher number the more you will see of the object behind. 70% is a big no, you will pretty much see everything, even if it’s turned off.
I would suggest 15% or 20%, if the room you are going to place the mirror is bright/really bright, I would go with the higher number. If it’s darker I would go with 15%.

And Have you actually asked any glass businesses if they can order it for you? Most major glass producers have a two-way mirror option.

You would do well with 15% or 20%. Certainly not 70%.

But if your frame is exactly fit for your LCD size, so there is no remained area beside LCD, higher transfer rate could be nicer. It could help clearer visibility. However, It depends on your conditions.

The room would be a bedroom so average brightness. I have emailed about 10 custom glass and window companies and waiting to here back. The one that did get back to me is $200+ for a 24x36" so its likely out of my budget.
