Pegasi 2 Review: Worth the Investment for Your Sleep?

In our quest to review all of the light therapy options on the market, we had to get our hands on the Pegasi 2, so here it is!

Long story short, it’s not worth buying. You’re much better off with either the AYO or the Luminette 3, but if you’d like to find out why, read on!

The Pegasi 2 Glasses

The Pegasi 2 “Dream Glasses” are a smart device designed to help users align their circadian rhythm with a green-turquoise light.

The first version has since been discontinued and the Chinese company behind the Pegasi device only links out to the new version we’re reviewing here.

You’d get these glasses if the Re-Timer and AYO glasses had a baby since they’ve got the spectrum of the Re-Timer but a design similar to that of the AYO.

But let’s get into what you get in the package:

Inside you’ll find:

• The Pegasi 2 glasses
• Fold up case
• Micro-USB charging cable

Yeah, micro-USB… not crazy about it!

The glasses themselves are quite built nicely and look pretty slick though I will say.

The Pegasi comes with a carrying case that leaves a little to be desired, but it does get the job done.

They kind of just barely fit in there, and once folded up the case itself feels a little bit flimsy, but there’s enough room for a USB cable so it works.

The Pegasi App

These glasses are “Bluetooth “smart” so they do emit Bluetooth radiation, however, they only do so when a mode is changed.

We measured these using a GQ EMF 390 and found that during use they don’t emit any radiation, which is awesome!

The “smart” functionality just means you need an app to change the brightness and duration settings on the device.

This app is only available on iOS however, so if you’re an Android user, you’re stuck with the one setting they defaulted to… which is the standard 30-minute session.

The app also comes with a jet lag tool which is kind of cool and useful but it’s also very simple and once you understand how it works it’s not so hard to just formulate a plan on your own.

How Effective Is the Pegasi?

I the beginning of this review I mentioned that the Pegasi 2 wasn’t worth buying. We’ll get into that now.

Like most of our glasses, we put these through some real scientific testing using our spectrometer-equipped mannequin head Henry!

Henry allows us to test the spectral qualities of these light therapy devices at the location of the eyes. We can then compare them to each other.

It’s unclear just how many LEDs the Pegasi utilizes but they do emit a very similar wavelength of light to the Re-Timer glasses.

This light is a green-turquoise color that peaks at around 505nm, which is just a bit greener than the Re-Timer’s 501nm peak.

We took readings of all three brightness levels and got the following measurements:

The Pegasi 2 on their low setting fail to hit the recommended CS score of 0.3 so I wouldn’t recommend using them like that.

However on the high 20-minute setting, they do perform alright, and they should work to shift your circadian rhythm when used in the morning or evening. Although they’re still not nearly as effective as the Luminette or AYO, so I still see no reason to get them.

How They Compare

As we mentioned, the Pegasi 2 will give you over 15 sessions on a single charge, that’s over twice as much as the other popular brands, but how?

Because they’re weak yo.

If we compare these to the Re-Timer, which uses a similar wavelength of light, we can see that even on its brightest setting the Pergasi glasses just get smoked.

So yeah, just not a fan. For the price, you’re much better off with other options.

My Final Thoughts on the Pegasi 2

It’s cool looking and comfortable, but that’s about it.
