Verilux HappyLight Compact review

The Verilux HappyLight Compact delivered a surprisingly decent performance, but we wouldn't recommend it for daily therapy sessions.

Our Verdict

The Verilux HappyLight Compact isn't built to be the brightest light therapy lamp; rather, it's designed to be portable. Still, it performed better than Verilux's full-size version.

For

  • • Performs well for its size

Against

  • • Brightness reach is subpar

Verilux HappyLight Compact: Overview

We have tested both the Verilux HappyLight Compact and its larger cousin, the HappyLight Full-Size. Surprisingly, the Compact was the better-performing lamp, despite being much smaller. 

That said, the light’s performance was still not good enough to make it useful for daily sessions, and therefore does not make it onto our list of the best therapy lamps – though its compact design makes it great to keep in the office or to take on trips to alleviate symptoms of jet lag.

Verilux HappyLight Compact: Features

As the name suggests, the HappyLight Compact is a small device – just 7.4 inches in height and 1.5lb in weight. As such, it can be easily transported from one place to another in a holdall or carry bag. 

This instant-on lamp comes with an energy-efficient 26W bulb and an Optix glare-control lens, while its on-board Flicker Elimination Technology means that you don't have to worry about irksome light twitching.

Verilux HappyLight Compact: Performance

The HappyLight Compact is one of the few lamps not advertised as a 10,000-lux light therapy box. Rather, the manufacturer suggests that longer sessions with this light have the same effect as a 10,000-lux light. This is true. You can get the same benefits from 5,000 lux as 10,000 lux – you just need to extend the time you sit in the light.

However, in our tests, the lamp produced 10,000 lux – though the reach was just 4.25 inches. At 16 inches, it had a 750-lux brightness, which is far below the recommended level. This means you have to sit very close to the lamp, even to get just 5,000 lux. Even at a foot away, the light's brightness was less than 2,000 lux. The HappyLight Full-Size was much worse. It had a 10,000-lux reach of just 2.5 inches and measured just 200 lux at 16 inches.

The HappyLight Compact has a color temperature of 6,500 Kelvin. That’s 1,500 Kelvin over the recommended range set by the Center for Environmental Therapeutics (CET), an organization of experts on light therapy. Despite being free of UV radiation, the CET doesn’t recommend cooler, bluish lights over 5,000 Kelvin because they can cause aversive glare and potentially damage your retinas if you take photosensitizing medications. The full-spectrum fluorescent light bulbs don't seem particularly blue until you see them turned on next to other light therapy lamps.

This Verilux HappyLight had an interesting heat output. The lamp’s surface reached 135 degrees Fahrenheit. And while it’s certainly not the hottest lamp out there, it's plenty hot enough. However, when we aimed it at a wall from 16 inches away, it only increased the wall’s surface temperature by 0.25 degrees. That isn’t significant enough to feel. So, while the lamp itself gets pretty warm, the heat dissipates quickly and shouldn't make you uncomfortably hot during therapy sessions.

Should you buy the Verilux HappyLight Compact?

The HappyLight Compact performed surprisingly well for its size. In fact, it was brighter than even its Full-Size counterpart. However, its light lacks the reach to provide the necessary brightness at a comfortable distance, so you have to extend your therapy sessions.
