As one of its Lead-Up to Prime Day Deals, and via select Alexa-enabled devices, Amazon offers Prime members the Philips Hue Go Portable Light for $44.99 with free shipping. (To order, say "Alexa, order a Philips Hue Go;" link is for reference only.) That's $4 under our mention from two days ago and the lowest price we could find today by $15. It features up to three hours of battery life and smartphone control via iOS or Android app. It's also Alexa-compatible.
