Score Breakdown
This verdict is based on the manufacturer's stated specifications, the current Amazon listing and its product images, the confirmed materials and design, real buyer ratings, and our research into the product category. Scores are consistent editorial judgments, not laboratory measurements, and we did not receive a paid sample.
Key Features
Switches to battery if power cuts.
3 duration and brightness settings.
Screws in like an ordinary bulb.
6 hooks, 3 plug caps.
12W draw during normal use.
Design and Build Quality
Each bulb houses a 1500mAh battery and measures about 5.5 inches tall and 2.7 inches wide, with the 6 pack weighing 1.48 pounds total.
The set includes 6 portable power hooks for handheld or hanging use during an outage, plus 3 plug caps that let the bulb's battery be tapped through an outlet-style adapter.
Performance in Everyday Use
Once the power cuts and the switch stays on, the bulb automatically lights, offering up to 14 hours of runtime across 3 selectable duration and brightness combinations of 100%, 50% and 10%.
During normal use, the bulb outputs 850 lumens at 6000K from 12W of power, which the feature text states saves at least 80% on electricity compared with an 80W bulb, while the title separately lists it as a 60W equivalent.

Who Should Buy It
- Homes wanting blackout-ready lighting in multiple rooms
- Basements, hallways and storage areas
- Camping and hiking trips
- Storm and hurricane preparedness
- Fixtures that need a dimmable bulb, since brightness here is adjusted through 3 fixed levels rather than a smooth dimmer
- The title states a 60W equivalent while the feature text separately states an 80W equivalent for the same 12W bulb
- Not dimmable in the traditional sense, limited to 3 fixed brightness levels rather than a smooth dimmer
- Only 3 plug caps are included for 6 bulbs, so not every bulb can use the plug cap method at once
- Sold only in White on this listing
