Our recommendation
Buy the Circadian Optics Lumos 2.0 if you value the longer track record, folding portability, and color temperatures. Buy the Erligpowht if you want the thinner tablet panel: touch dimming, 4 timer settings, and a rotating stand at a lower price. Both deliver 10,000 lux with timers; the differences are brand history versus thinness and value.
Features
Both offer 10,000 lux and 15/30/45/60-minute timers. The Lumos adds 3 color temperatures and a folding design that packs better for travel. The Erligpowht counters with touch dimming across 3 brightness levels and a rotating stand. Feature parity is otherwise close.
Brand and reliability
Circadian Optics has sold therapy lamps longer and has more user history behind it. Erligpowht is a newer Amazon-native brand with less long-term data but strong recent sales. For a device you will use daily for years, track record is worth weighing.
Design
The Lumos folds flat for bags; the Erligpowht is a rigid tablet about 0.59 inches thin with a rotating stand. Both suit desks and nightstands. Neither matches the Carex's field size, which is the expected trade at budget prices.
Choose Circadian Optics Lumos 2.0 if…
- You want the brand with more user history
- Portability and folding design matter
- You prefer established therapy-lamp makers
Choose Erligpowht Light Therapy Lamp if…
- Touch dimming and a rotating stand appeal to you
- You want maximum features per dollar
- You prefer the slimmest tablet profile
Questions, answered
Are budget therapy lamps effective?
Yes, if they truly deliver 10,000 lux at a usable distance. Both of these document that output. Price in this category buys features and brand history, not the core therapeutic dose.
Which has the better timer?
Equivalent: both offer 15, 30, 45, and 60-minute presets. Use 30 minutes for the standard protocol.
Do I need the memory function?
It is convenience, not therapy: one touch restores your brightness, color, and timer. Nice if multiple people share the lamp with different preferences.
