Built for everyday sockets
The AT19 from LUMIFARO keeps the shape everyone knows — the classic A-style household lamp — and packs LED technology inside it. Its clear bulb finish means the lamp looks good in open fixtures where the bulb is part of the design: schoolhouse pendants, bare-socket sconces, cage fixtures, vanity bars and farmhouse chandeliers. At 102 mm in height and 60 mm in diameter, it slips into shades, glass globes and recessed cans without crowding the housing, so you are not measuring twice before you buy a case.
Light quality you can trust
This bulb puts out 800 lumens for only 8 watts, which is the sweet spot for general-purpose lighting in living spaces and work areas. Its CRI 80 rendering keeps colours honest — useful when you are matching paint in a hallway, plating food in a small kitchen, or displaying merchandise on a shelf. The AT19 family is offered in 3000K and 4000K; LEDAT198W40K is the 4000K neutral white, the temperature most people choose for kitchens, bathrooms, garages, basements, workshops and commercial rooms where clarity matters more than cosiness. The photometric report in the spec sheet lists an average beam angle at 50% of 282.3°, which tells you this lamp spreads light broadly rather than throwing a narrow spot — exactly what you want for ambient and general illumination.

Dimming and installation
Because the AT19 is a dimmable LED bulb, it works with most dimmers on the market, but LED loads behave differently than incandescent ones. The manufacturer's guidance is clear: dimmers generally carry a maximum 150-watt rating for LED bulbs, and you should not exceed 80% of that capacity if you want to avoid flicker when the dimmer is at its lowest setting. Plan your circuits accordingly and you will get smooth, quiet dimming. Installation itself is as easy as changing a bulb — cut the power, thread it in, restore power — which makes the AT19 the go-to for rental turnovers, condo refreshes and quick maintenance calls where a ladder and five minutes are all you have.
Applications and documentation
Think of the whole project: a Montréal triplex where every ceiling fixture gets the same neutral white, a garage with four bare sockets that finally reads bright at night, a café with exposed pendants over the counter, a salon mirror bar, a stairwell in a small office building, a basement workshop where 800 lumens per socket keeps the bench clear of shadows. Using one A19 LED bulb throughout keeps colour temperature consistent from room to room — the detail that makes a renovation look professionally done. The full technical spec sheet (LEDAT198W40K Spec Sheet) is available in the Documentation tab of this page, with the luminous intensity distribution diagram and the illumination-versus-distance table if you need to document the job for a client.
