Good
- Lowest brand-listed price per bulb here, about $15 in the 2-pack or $12.50 in the 4-pack
- 1400K "Campfire" mode is warmer than the warm end of LIFX (1500K)
- Mode memory means the bulb comes back on in the last setting you used
Not so good
- No lumen figure for any mode, so you cannot judge how bright or dim it is
- Brightest mode is 2700K, ordinary warm white rather than a bright daytime light
- The "zero blue light" claim for the 1400K mode has no published spectrum behind it
- Changing modes means flicking the wall switch, which is easy to forget each evening
This is the cheapest way on this list to get one bulb that does both an ordinary warm white and a very warm evening light. Hooga sells it in a 2-pack for $29.99 (about $15 a bulb) or a 4-pack for $49.99, and it is also listed on Amazon. There is no app, hub or Wi-Fi: you cycle between 2700K, 2100K and a 1400K “Campfire” mode by flicking your existing wall switch, and the bulb remembers the last mode.
The 1400K mode is the reason to buy it. Hooga says it has “zero blue light”, and 1400K is warmer than the warm end of the LIFX bulb on this list. Hooga does not publish a spectrum to back that up, so treat it as a brand claim.
What it does badly: Hooga gives no lumen figure for any mode, so you cannot tell how bright the bulb is or how dim the Campfire mode gets. Hooga also calls it “fully dimmable” and mentions “3 brightness settings” without explaining either. The brightest mode is 2700K, the colour of a standard soft white bulb, so it does nothing to boost daytime light. Calling it “full spectrum” adds little; the brand gives no colour rendering figure.
How it compares: the Bon Charge Full Spectrum bulb works the same way with a switch, goes cooler in the day (5000K) and publishes lumens per mode, but costs $34.99 for one bulb and its evening mode stops at 1700K. A smart bulb such as LIFX SuperColor costs more but changes on a schedule, so you do not have to remember to switch it.
Hooga also sells a single-colour red sleep bulb on Amazon; see the Hooga Sleep Light Bulb.
