While most circadian alignment protocols rely on targeting the melanopsin cells in your eye (the ones most sensitive to blue light), the Tuo bulb uses a new technique… The Overview The Tuo delivers specialized color-opponent light that has been shown to produce stronger phase-shifting and melatonin-suppression effects than conventional bright light therapy using much less overall light, making it a great option for anyone who finds bright SAD lamps overwhelming. However, visible flickering, especially on higher settings, can be bothersome as well. Pros Cons The Tuo Circadian Smart Bulb Tuo sells just one A21-shaped light bulb and an optional wooden desk lamp holder. I bought both to try out the full set. The shadeless lamp is a bit odd at first glance, but this is…

The Bedtime Bulb v2 by Restful is out! (for pre-order anyway) And we’re gonna take a close look at what it’s got to offer. The Overview The Bedtime Bulb combines LED efficiency with incandescent warmth, delivering high-CRI, full-spectrum infrared light.

Alright, in this article, we’ll take an in-depth look at the Northern Light Technologies lamps and how they compare to all the other SAD lamps we’ve tested thus far. The Lamps Northern Light Technology is a Canadian SAD lamp company that has been around for a while, and its more industrial design choices indeed show this. For this review, I got my hands on every model they sell, nothing left out! Something to note: These all utilize tube lights, except the Luxor models, which actually use E26 light bulbs. This means, however, that they don’t emit perfectly diffused light, unlike many of the LED panel-based SAD lamps available. The actual light sources themselves appear something like this during use: The benefit of this approach is…

I ran across VivaRays, which sells “UV-transmitting” prescription glasses, as well as their blue blocker products. Very interesting! However, since there is no real data or measurements on the website about the type of light allowed through, I purchased some for myself to test. Let’s take a look at the results! The Overview VivaRays offer a solid range of magnetic blue blockers, and their lenses performed well in our tests. While their UVA claims are overstated, they do transmit more UVA than standard lenses. If you wear prescription glasses and want a UVA-friendly option with attachable blue blockers, these are the top pick. Use code OYB10 for 10% off! The 4-in-1 VivaRays VivaRays sells individual blue blockers, as well as 2-in-1, 3-in-1, and 4-in-1 options,…

I think the right word is disappointed, but I could use many others. NIRA isn’t a bad product per se, but its marketing is full of lies and misleading claims. Since I’ve been asked a few times now, let’s examine the science of NIRA in depth. What is NIRA? NIRA is a new lighting company that mainly sells “Near-infrared enhanced” LEDs, but it also sells DC-powered lights. Since NIRA’s main selling point is its light spectrum, I’m going to examine a couple of its normal light bulbs. Let’s Examine NIRA’s Spectrum Let’s start with the biggest lie I’ve ever seen in the lighting industry: NIRA emits full-spectrum light all the way out to 3000nm! Here is their marketing promo, which can be seen on this…

Alright, I finally bought and tested the Sky Portal from Chroma! The 2.1 version, anyway. Let’s dive into the build, spectral testing, and usability, and see how it stacks up. The Overview The Sky Portal 2.1 is a uniquely designed monitor light that stands out for its spectral output, which pairs exceptionally well with screens to reduce eye strain. Its warm amber mode is a standout feature, making evening work much more comfortable without disrupting circadian rhythms. Plus, it’s completely flicker-free, ensuring a smooth and comfortable lighting experience. That said, for the price, it could be a bit brighter, and the build quality leaves some room for improvement. The rear-mounted controls, while functional, can be a bit inconvenient to access. Despite these minor drawbacks, the…
