Product: I am afraid I am no expert, photographer, or lighting engineer/technician, so only a civilian perspective...
Excellent quality product, which did not splinter, crack, or disintegrate even when it was cut into small circles of 70mm diameter.
I wanted to soften the six downlighting LED "bulbs" in a dimming, height-adjustable, six light chandelier, above a round dining table. The six light sources had covers held in with mini hex screws so cut a 7cm disc from this inexpensive roll of (what seems to be high-quality) film/filter and inserted them just inside the opaque covers turning 3000+K lighting into 2700K lighting, which has made enough difference for me to keep the light fitting, which otherwise would be on its way back to John Lewis.
Sparks Supermarket Lighting: 9/10 for this order/experience (my first purchase). I ordered in the morning and it arrived in excellent, strong packaging that was eco-conscious in that it was size appropriate, strong without needing further padding internally and plain brown paper/card (which looked recycled) yet smart and sleek-looking.
They know what they are doing.
The 'LEE ZIRCON 809 WARM AMBER 8' filter seemed insanely good value -£4 something.
Next Day or 1-2 Delivery cost more than the item at £q5-6 but did arrive the following day as promised.
A quick query via email was answered, swiftly, deftly, and politely.
Highly recommend.
