Does this bulb need a hub?

No. It connects directly to 2.4 GHz Wi-Fi and is controlled through the WiZ app.

1600 lumens, roughly equal to a 100W incandescent, in an A21 bulb.

It does tunable white only, from about 2200K warm to 6500K daylight. There is no RGB color.

It uses a standard E26 screw base, but the A21 body is about 5.45 inches tall, so check tight shades.

Is $31.44 a good price?

It is the top of its recent range, so wait for a drop if you are not in a hurry.

Does it work with Alexa and Google Home?

Yes, and with Siri Shortcuts. Set up in the WiZ app first, then link the account.

Our take on the Wiz Smart Light Bulb

The WiZ 604280 is a 100W-equivalent smart LED in an A21 body, putting out 1600 lumens of tunable white light from 2200K warm to 6500K daylight. It screws into a standard E26 socket and connects over Wi-Fi, so it needs no hub. It is a single bulb, not a multipack, and at $31.44 at Walmart as of November 7, 2026 it sits at the top of its recent range, so it is not a bargain moment.
