Kasa Filament Smart Bulb deliver quality light, but neither is very bright

TP-Link is the latest to the party with its matched pair of Kasa Smart Vintage LED Filament Bulbs, both of which are affordable Wi-Fi-ready devices, albeit rather limited in features. These bulbs are both white-only and each comes permanently tuned to a specific color temperature: The KL50 is a soft (but still warm) white, the KL60 is an even warmer amber. Aside from that, they are largely distinguished by their overall power. The KL50 emits 600 lumens, but the KL60 puts out just 400. Both of those values are rather low, however, making these bulbs best suited for accent use rather than full-on task lights. Both bulbs can be dimmed in software—and with either Amazon Alexa or Google Assistant—but not via a hardware switch.
