A red light therapy bulb screws into a lamp socket and shines red and near infrared light on a small area. Most are LED bulbs at 660nm and 850nm; a few are incandescent heat bulbs that give off near infrared along with a lot of heat. Neither is the same as a red sleep bulb, which is a dim colored light for the bedroom.
This roundup scores six bulbs sold on Amazon on what each listing states. For larger devices, see targeted red light devices and full body panels. Listings were collected 4 October 2026.

What each listing states
| Bulb | Type | Wavelengths | Irradiance stated | Power | Warranty |
|---|---|---|---|---|---|
| hooga HG24 | LED | 660, 850nm | 120 and 85 mW/cm² | Not stated | 1 year |
| Generic 24 LED Lamp | LED | 660, 850nm | About 75 mW/cm² at 6 in | Not stated | 12 months |
| Zarbaha P2 | LED, fan | 660, 850nm | Up to 242 mW/cm² | 54 W | 12 months |
| wolezek 18 LED | LED | 660, 850nm | Not stated | 36 W | Not stated |

| LifePro Infraglow | LED | 660, 850nm | Not stated | 24 W | Not stated |
An irradiance figure means little without a distance, because light falls off quickly as you move away. Only two listings here give one. See red light irradiance explained.
We read 20 listings. Eighteen state a wavelength and 5 an irradiance, 8 state a warranty, and none names an electrical safety listing or claims FDA clearance. Eight were red sleep bulbs at 625 to 670nm and 1 to 9 W. Those are bedroom lights, not therapy devices, and we left them out.
What it costs to run
Four bulbs state their power. At full rated power, using 18.34 cents per kWh, the US residential average for June 2026 from the Energy Information Administration:
| Product | Rated power | Per one hour | Per month, 4 sessions a week |
|---|---|---|---|
| RubyLux NIR-A 250W | 250 W | 5 cents | $0.79 |
| Zarbaha P2 | 54 W | 1 cents | $0.17 |
| wolezek 18 LED | 36 W | 1 cents | $0.11 |
| LifePro Infraglow | 24 W | 0 cents | $0.08 |
LED bulbs cost pennies a month. The 250 W heat bulb costs more, though still little at short sessions.
Using a bulb safely
- Protect your eyes. Near infrared is invisible, so a bulb can look dim while putting out a lot of light. Use goggles; see red light therapy goggles.
- Check the socket and fixture are rated for the bulb’s wattage, especially the 250 W heat bulb, which needs a heat rated fixture.
- Check the voltage. Two LED bulbs here list 240 volts in their data; US sockets are 120 volts.
- Keep heat bulbs away from skin, fabric and anything flammable, and do not leave them on unattended.
Score notes
The Chill Score weighs performance 35, build 25, value 25, safety certifications 10 where it applies and warranty 5. Here, performance covers stated wavelengths, irradiance with a distance, LED count and power. No listing names an electrical safety listing, so all score zero there.

|---|---|---|---|---|---|---|

| LifePro Infraglow | 9.4 | 26 | 20 | 19 | 0 | 0 |
Scores run from 9.2 to 9.8: each product’s point total is placed on that range, so more points always means a higher score.
hooga and the unbranded 24 LED bulb lead on stated irradiance and warranties. Zarbaha is the most powerful LED bulb. RubyLux is a different tool, a heat bulb, and needs extra care.
Who should not buy one
If you want to cover your whole body, a single bulb is too small; see full body panels or mats. If you want a calm red light for sleep, buy a sleep bulb, not a therapy bulb. And if you cannot use eye protection, skip bright bulbs.
Common questions
Is a red sleep bulb the same as a therapy bulb?
No. Sleep bulbs are dim, 1 to 9 W, and meant for room lighting. Therapy bulbs are much brighter and use 660nm and 850nm LEDs or a heat filament.
LED or incandescent?
LED bulbs run cooler and use far less power. Incandescent near infrared bulbs add a lot of heat, which is why they are used in DIY saunas, but they need heat rated fixtures.
How far should I sit from the bulb?
Follow the maker’s distance. Light falls off fast with distance, so moving closer raises the dose sharply.
