Built for open, decorative fixtures
The LUMIFARO CTC LED bulb is designed to be seen. Its clear bulb colour leaves the light source visible, which is what gives chandeliers, exposed-bulb pendants and vanity bars their character — a frosted bulb simply can't do that. Compact at 95 mm by 35 mm, it slips into tight shades, small sconce cups and multi-arm fixtures where a bulky lamp would look wrong or wouldn't fit at all. Swapping a whole fixture is expensive and messy; swapping the bulb takes thirty seconds and changes the entire mood of a room.
Light quality and output
At 5.5 watts this bulb produces 500 lumens, a comfortable level for accent and ambient lighting in residential rooms and hospitality spaces. Its CRI of 80 keeps colours honest — important above a dining table, in a retail display or in a bathroom mirror where you judge colour every morning. This SKU is the 4000K neutral white version, a clean daylight-leaning tone that reads as bright and modern; the family is also offered in a warmer 2700K. The spec sheet includes a luminous intensity distribution diagram and a table of average and maximum illumination at heights from 1 m to 10 m, so designers can verify coverage before installing.

Dimming and installation notes
This is a dimmable LED bulb that works with most dimmers. The manufacturer notes that dimmers generally carry a maximum 150-watt rating for LED bulbs, and strongly recommends not exceeding 80% of that capacity to avoid flicker when the dimmer is at its lowest setting — as an example, a maximum of 15 8-watt PAR20 bulbs, for a total of 120 watts. Follow that rule of thumb when you calculate how many bulbs to put on one circuit and you'll get smooth, quiet dimming instead of shimmer. Installation is as simple as it gets: power off at the switch, let the old lamp cool, thread the new one in by hand, and power back up. Since it runs on standard 120 volts, no driver, transformer or rewiring is required.
Applications and documentation
Think of the places where the bulb is part of the design: a five-arm dining chandelier, a pair of bedside wall sconces, a row of glass pendants over a kitchen island, a bathroom vanity strip, a hallway lantern, or the open fixtures in a café, barber shop, boutique or hotel lobby. Property managers and contractors like standardizing on one 120V LED bulb across an entire building — fewer part numbers to stock, one predictable colour tone, and the 2-year warranty behind every unit. The full technical PDF (LEDCTC55W40K Spec Sheet) is available in the Documentation tab with the photometric diagram, illumination table and dimensions, so you can confirm every detail before you specify it for a project.
