Our take on the Satco S9580 4.5T10/LED/E26/27K 4.5 Watt T10 Medium LED 2700K - NOW S21344

The Satco S9580 is a 4.5-watt clear T10 tubular LED filament bulb with a medium E26 base. It puts out about 450 lumens of warm 2700K light in a full 360-degree spread, replacing a 40-watt incandescent while using a fraction of the power. It is dimmable, rated for enclosed fixtures and lasts a rated 15,000 hours. It suits exposed-bulb fixtures such as pendants, sconces and vanity bars where the filament look matters. Against Edison-style ST19 and A19 filament bulbs, the slim T10 tubular shape fits narrower fixtures, but its 80 CRI and non-compliant CEC status make it a plainer choice than high-CRI designer bulbs.
