    Default Feedback on 3M Polarizing Lights ...

    Hi to all,

    Thinking of getting a table lamp; would love to hear from users of the 3M ones ... are they really so good that they can command about 10 times the price of the cheap ones (less than S$20) which are found @ Ikea?

    TIA!

    I am interested to know too!

    For some reason, when I inspect the display sets, I think that piece of plastic covering the light bulb is all there is that makes the difference.

    I had been trying to justify the high cost for the past 2 years. Still cannot convince myself that it works. I remembered my primary school teacher says incandescent lamp is the best for eyes but its hot only.

    I tried so many times to read under the 3M lamp but I still see reflections. Maybe inventing(or is there already one out there) a pair of polarizing reading glasses would be better.

    Unless the surface is perfectly smooth and even at electron level, as soon as a polarised light hits a reflective surface, it gets scattered, thereby "de-polarised" to a certain extent, so you would still see some reflections/glare. Also do note that you should also have your ambient lights on so the polarising effect might be further reduced.

    IIRC some strobe technique book I read actually uses sheet polariser on studio strobes, I wonder if such sheets are available in Sg, could be a cheaper DIY option.

    However I do recommend using higher frequency (IIRC 100Hz or more) light source as reading light.
