BioLight Glow Portable Device

The Glow is the smallest thing BioLight builds: 6.2 in. by 3 in. by 0.53 in., 0.6 lbs, 18 LEDs at 1W each in 660nm red and 850nm near-infrared behind a 90 degree lens. There is one control, and it is the power button. No modes, no brightness steps, no pulse rate. Press it and an automatic 10 minute cycle runs on the internal battery, which holds about 80 minutes of use and refills in about 60 over USB Type-C.

Its published output is the lowest of BioLight's three handhelds and they publish it at two distances: 18.5 mW/cm2 with the device against the skin, and 1.6 mW/cm2 at 6 in. away. BioLight is direct about what follows from the second figure, stating on their own page that eye protection is not required with this device because its irradiance is very low. Those numbers are what they are, and they set how the Glow is used: held on one small area, in contact, for the length of one cycle. That is the device. It fits in a pocket, it charges off the same cable as a phone, and it asks nothing of you beyond pressing the button.

How it is used

A Contact Device, by Its Own Two Numbers

BioLight publishes the Glow's output at contact and at 6 in. The gap between those two figures is the most useful thing on the spec sheet, because it decides how the device is held.

🖐

Held Against the Skin, or Set at a Distance

Two ways exist to run any light device: in contact with the surface, or standing off from it. Panels are built for the second, which is why BioLight quotes them at 6 in. and sells them with stands. The Glow is built for the first, and its own published pair says so plainly: 18.5 mW/cm2 with the emitting face on the skin, 1.6 mW/cm2 six inches back. The optics explain the shape of that: a 90 degree lens is a wide cone, wider than the 60 degree lens on BioLight's Shine and far wider than the 30 degree lens on their panels, and a wide cone puts light on a broad area close in. So plan contact sessions on one small area at a time. If you buy it with the stand and set it back, the figure you are working with is 1.6 mW/cm2 at 6 in., and the 18.5 one no longer applies. Neither figure is right or wrong; they belong to two different ways of holding the same device, and BioLight publishes both so you can choose knowingly.

18.5 at contact, 1.6 at 6 in.

⏱

One Button and One Ten Minute Cycle

BioLight removed the mode selector from this model on purpose and says so on their page: there are no light setting options to choose between, so the question of red only, near-infrared only or both never arises. Power on and the device runs a fixed automatic 10 minute cycle at one output, then stops. Their stated frequency guidance is 3 to 5 sessions per week. Nothing on this device dims, pulses or switches wavelength, which is the trade for its size and for a control surface with one button on it.

Automatic 10 minute cycle

🌈

18 Emitters at 660nm and 850nm

Eighteen LEDs at 1W each, running 660nm red and 850nm near-infrared together across a face measuring 6.2 in. by 3 in. Both wavelengths are on whenever the device is on, since there is no way to select one. BioLight does not apply their Dual LED naming to this model the way they do to the Shine, the ReStore and the ReCharge, and they publish no diode part, bin or chip configuration for it.

Battery, EMF and BioLight's Note on Eyewear

Eighty minutes of use per charge, about sixty minutes to refill over USB Type-C, which works out to roughly eight cycles between charges. Because nothing is drawing mains current while it runs, BioLight publishes flicker at 0 Hz and EMF emission at 0.0 microtesla at contact and gives the battery as the reason for both. They also state, in their own words, that eye protection is not required with this device because its light irradiance is very low, and no eyewear is included in the box.

The body

Half an Inch Thick and Ten Ounces Under a Pound

Measured, the Glow is 6.2 in. by 3 in. by 0.53 in. and weighs 0.6 lbs. Set it beside BioLight's Shine, which is 0.87 in. thick at 12.6 oz, and the Glow is the thinner of the two by a third. Eighteen LEDs at 1W each cover the face at 660nm red and 850nm near-infrared, behind a 90 degree lens on each emitter. BioLight publishes the output at contact as 18.5 mW/cm2 and at 6 in. as 1.6 mW/cm2. Both belong on any page that quotes either, since the pair is what tells you how to hold it.

BioLight Glow running a session against the skin

The cycle

Press Once, Ten Minutes, Done

There is one control on the Glow and it turns the device on. BioLight states plainly on their page that no light setting options exist on this model, so nothing has to be chosen before a session starts. The automatic timer runs 10 minutes and ends the cycle. Their stated frequency guidance is 3 to 5 sessions a week. Eighty minutes of battery covers about eight of those cycles, and a full recharge takes about an hour over USB Type-C, the same connector most phones use. Where the Shine gives you four modes and a fixed 40 Hz pulse setting to think about, the Glow gives you a button.

A Silicone Case, a Cable and an Optional Stand

Four items ship as standard: the Glow, a silicone protective case, a USB Type-C charging cord, the user manual and BioLight's Red Light Therapy Treatment Protocols ebook. A stand is offered as a separate option at the point of purchase, and it is genuinely separate, since it does not appear in the base package list. No eyewear is included, and BioLight's stated reason is the device's low irradiance. BioLight publishes a 60 day trial period and a limited 3 year warranty for the Glow, and publishes no diode lifespan figure for it, which is the one row their handheld pages usually fill.

Four Targeted BioLight Devices, Side by Side

The Glow and the Shine are both published at 6 in., so those two figures can be read against each other. The Beam's number is a stated floor and the Guardian's is quoted at contact only, so neither is set against them here.

Questions

Frequently Asked Questions

BioLight publishes two figures: 18.5 mW/cm2 at 0 in., meaning the device against the skin, and 1.6 mW/cm2 at 6 in. Both are theirs and both need their distance printed with them. There is no brightness control, so there are no steps beneath either figure. BioLight publishes no measurement method, meter or laboratory name for them.

That word comes from BioLight's own product title, which this listing inherited, and BioLight makes no pain claim anywhere in the body of their Glow page. We are not repeating any outcome claim behind it. What is publishable about this device is its specification: 18 LEDs at 660nm and 850nm, 18.5 mW/cm2 at contact and 1.6 mW/cm2 at 6 in., a 90 degree lens, a fixed 10 minute cycle, 0.53 in. thick at 0.6 lbs. We have flagged the title itself for rewriting.

BioLight's two published figures point to contact. At 0 in. the device is rated 18.5 mW/cm2; six inches back it is rated 1.6 mW/cm2. A 90 degree lens spreads a wide cone, so the light covers a broad area close in. If you add the stand and set the device away from you, the 1.6 mW/cm2 figure is the one that applies to that session.

BioLight states on their own page that eye protection is not required with this device, because its light irradiance is very low. That is their statement, quoted here as theirs, and no eyewear ships in the box. Their panels are sold with protective eyewear included; this device is not. If you would sooner wear eyewear anyway, nothing about the device stops you.

The timer is fixed: an automatic 10 minute cycle that runs and then stops. BioLight's stated frequency guidance is 3 to 5 times per week. That guidance is BioLight's own.

No, and BioLight says so directly: there are no light setting options on the Glow. Red at 660nm and near-infrared at 850nm run together whenever the device is on. There is no red-only setting, no near-infrared-only setting, no brightness adjustment and no pulse frequency.

Size, controls and output. The Glow is 0.53 in. thick at 0.6 lbs with 18 LEDs at 660nm, one button and a fixed 10 minute cycle. The Shine is 0.87 in. thick at 12.6 oz with 15 LEDs at 630nm, four selectable modes including a fixed 40 Hz pulsed setting, and no timer. At 6 in. BioLight publishes 1.6 mW/cm2 for the Glow and 4.2 mW/cm2 for the Shine, which is a fair comparison because both are quoted at the same distance.

18 LEDs at 1W each. BioLight's description buries the count inside a power line, but their specification block states it plainly. The emitting face is 6.2 in. by 3 in., so those 18 emitters sit at a higher density than the 15 on the Shine's slightly larger face.

80 minutes of use per charge, recharging in about 60 minutes over USB Type-C. At a fixed 10 minute cycle that is roughly eight sessions between charges.

EMF emission is given as 0.0 microtesla at contact and flicker as 0 Hz. BioLight attributes both to the internal battery, since no mains current runs through the device while it is on. No laboratory name, report number or date is published alongside either figure.

BioLight states a limited 3 year warranty and a 60 day trial period. They publish no diode lifespan figure for the Glow, which is unusual for their handhelds: the Shine is published at 20,000 hours and their panels at 100,000. We have asked BioLight for it.
