E14-AC4020 single-colour pixel bulb

A bulb with a board inside

The E14-AC4020 keeps the oldest fairground form — a screw-base bulb — and replaces the filament with a printed circuit board carrying twenty LEDs in a single colour. The result outlines a Ferris wheel rim or a carousel canopy in points of steady colour that read across a fairground, while remaining, mechanically, a bulb: it screws into an E14 holder and is replaced like one.

The specification graphic on this page, reproduced from the maker's product page, draws the bulb's dimensions beside its parameter table — the two input voltages it runs on, its colour set and its working-temperature range among them.

Specification and packing

Packing data

Notes on this model

• E14 lamp holder with a PCB carrying 20 SMD2835 LEDs.
• Runs on 24V or 60V — state which voltage your structure uses when you inquire.
• Single colour per bulb: red, green, blue, yellow or white.

Five colours, chosen bulb by bulb

Colour on this model is a purchasing decision, not a setting: red, green, blue, yellow or white, fixed per bulb at the order. Structures are coloured the way they are drawn — one colour per rim, alternating colours along a canopy edge, white points with coloured accents — and the count per colour belongs in the inquiry alongside the total.

The bulb runs on either of two voltages, so state which voltage your structure uses when you inquire. That detail matters more than it looks: a rim wired for one voltage is not a rim that can be re-lamped with the other, and the packing data on this page — hundreds of bulbs to a carton — describes orders where a mixed shipment would be a long evening's sorting.

Rims, canopies and ride outlines

The published applications are amusement parks, carousels and Ferris wheels — structures whose lighting is a drawing made of points. At those viewing distances a steady colour per point is not a limitation; it is the aesthetic the structures were built around, and it is why this technology survives alongside programmable pixels rather than being replaced by them.

Maintenance closes the case. A failed unit is unscrewed and replaced between rides, by the crew that runs the structure, with no electrician, no programmer and no spare-parts system beyond a box of bulbs in the right colours and the right voltage. It is worth pricing that simplicity in full when this model is compared with programmable alternatives: the alternatives buy effects this bulb cannot produce, and the bulb buys service measured by its stated lifespan — at least 50,000 hours in its own table — across evenings on which nothing about its lighting needs to be understood by anyone on site beyond which colour goes in which socket.
