Hooga
HG24 4-in-1 review
A light bulb rather than a panel, and priced accordingly. Worth listing because its measured output sits unusually close to the brand's own figure, which is rare at any price.
DISCLOSURE — we earn commission on purchases made through our links, at no extra cost to you. Rankings come from specifications and measurements, never from commission rates.
What we like
- Forty dollars, and its measured peak came within about ten percent of what Hooga advertises
- Four wavelengths including 415nm blue and 590nm yellow that panels rarely carry
- Screws into a standard E26 or E27 lamp base, no mounting required
What to know
- 12 LEDs at 2 W each is a fraction of a panel's total dose
- Hooga makes no FDA claim of any kind and states the product is for general wellness only
- Only a peak reading was published by the independent tester, with no nine-point average
