Customer Reviews (4.8 / 5 · 5 reviews)

Violet ★★★★★

The red tint is exactly right—my prints stay crisp with no fogging, even after an hour under the K4018. Snaps on securely with no wobble, and the plastic feels sturdy enough to last years in the darkroom.

David ★★★★★

Fits perfectly onto my K4018 safelight without any wobble, and the red tint is just dark enough to see my paper trays clearly without fogging any of my Ilford paper. Not the cheapest filter, but the solid build feels like it will last years.

Olivia ★★★★★

The deep red glow is exactly what I needed – it’s bright enough to see my trays clearly, yet I’ve had no issues with paper fogging even after long sessions. The fit onto the K4018 housing was snug and perfect right out of the box.
