SATCO Lighting S21284 4W B11 LED, Clear, Medium Base, 90 CRI, 2700K, 120V

Both are covered. The lamp is enclosed rated, so it can go in a sealed globe or lantern without the heat shortening its life, and it carries a wet location rating for indoor or outdoor use. That makes it workable in exterior porch lanterns, post lights, and coach lights exposed to rain.

It replaces a 40W incandescent B11, drawing 4W at 350 lumens. For a property manager relamping a corridor or lobby fixture, that is a roughly 90 percent cut in connected load per socket at the same light output, with 15,000 hours rated life instead of the 1,000 or so a candle incandescent gives.

The lamp is dimmable on 120V, 60Hz line voltage. It is not a three-way lamp, so it will not step through the three levels in a 3-way socket, and it is not CCT selectable, so the color stays at 2700K through the dim range. On older incandescent dimmers a 4W load can sit below the dimmer's minimum, so pair it with an LED-rated dimmer or gang several lamps on the same circuit.

Yes, it is a clear LED filament lamp, so the lit filament strips are visible through the glass the way a vintage candle incandescent looks. The 2700K color and 90 CRI keep skin tones and wood finishes true, which matters in hospitality and multi-family common areas where the bulb is on display. Beam spread is 300 degrees, so it throws light nearly all the way around rather than in one direction.

Burning position is universal, so base-up, base-down, or horizontal all work. That covers chandeliers with upturned candle cups, wall sconces pointing down, and horizontal lantern sockets without derating the lamp.

Title 24 compliant, per Satco's data. It is not DLC listed, so if your rebate program or utility incentive requires a DLC qualified product, this lamp will not qualify for it. The lamp is FCC compliant.

Each lamp draws 0.033A at 120V, so the lamp current itself is negligible for an MRO electrician doing a chandelier retrofit. A 12-light fixture pulls under half an amp. Circuit loading is almost never the constraint on these; the dimmer's minimum load usually is.

Glass envelope on a nickel plated aluminum base, weighing 0.04 lb per lamp. The metal base dissipates heat better than all-plastic candle lamps, which is part of what lets it carry the enclosed fixture rating. It is made in China.
