A lighted 4x lens for routine plant checks

The Carson SV-40 is a handheld 4x LED magnifier with a 3 inch aspheric lens. It suits daily plant checks where the goal is to look closely at leaves, labels, tray notes, seed packets, and sticky-card surfaces.

The 3 inch lens gives the tool a comfortable view of flat samples. It can sit beside a plant-care notebook, tray stack, or greenhouse shelf where quick observation happens often.

A simple tool for shelf-side questions

Garden questions often start small: a pale spot on a leaf, a mark on a label, a tiny speck on a sticky card, or a tray note that needs a second look. The SV-40 adds light and magnification to those moments.

Use the LED when a shelf is shaded or the leaf underside needs a brighter view. Keep the magnifier in a dry caddy near gloves, cards, and notes.
