Yugster offers the refurbished second-generation Philips Hue Stand Alone Bridge for $34.99 with free shipping. That's $16 under the best price we could find for a new one, although we saw a refurb for $6 less in April. It controls up to 50 lights via smartphone app, Alexa or Google Home voice control, or the bridge itself.

Note: A 90-day Yugster warranty applies.
