SATCO Lighting S21206 4W G16.5 LED, Clear, Candelabra Base, 90 CRI, 4000K, 120V

It replaces a 40 watt incandescent globe while drawing 4 watts, and puts out 350 lumens. Light output spreads over a 300 degree beam angle, so it fills a fixture the way a clear globe bulb does rather than throwing a directional beam.

Both are fine. The S21206 carries a wet location rating and is listed for indoor or outdoor use, so covered porch lanterns and exterior sconces are in scope. It is also an enclosed rated lamp, which means it can go inside a sealed or gasketed fixture where non-rated LEDs overheat and fail early. Burning position is universal, so base up, base down or horizontal all work.

4000K is a neutral white, noticeably crisper than the 2700K warm glow most people expect from a decorative chandelier. It suits lobbies, corridors, retail and task areas where you want a clean white light. For hospitality or residential spaces trying to match existing incandescent warmth, pick a warmer color temperature instead, because this lamp has a fixed 4000K output and is not CCT selectable. Color rendering is 90 CRI, so skin tones and finishes read accurately either way.

The lamp is dimmable. At 4 watts per bulb it draws very little, so on a legacy incandescent (leading edge) dimmer a small fixture count can fall under the dimmer's minimum load and flicker or buzz. An LED-rated dimmer, or enough lamps on the circuit, avoids that. It is not a three-way lamp, so do not put it in a three-way socket expecting stepped output.

Yes. It is an LED filament lamp in clear glass, so the filament strands are visible the way they are in a decorative incandescent. That matters in open chandeliers, exposed-bulb pendants and glass front fixtures where the lamp itself is part of the look. Construction is glass with a nickel plated aluminum base.

Title 24 compliant, yes, and it is FCC compliant as well. Useful if you are relamping a California property under code. It is not DLC listed, so if a utility rebate program requires a DLC qualified product, this lamp will not qualify for it.

Average rated life is 15,000 hours. On a corridor or exterior fixture running roughly 12 hours a day that is about three and a half years between relamps, which is the number to use when you are planning a building-wide candelabra changeout.
