300W TDP Infrared Physical Therapy Lamp CQ-29-1 for Pain Relief and Arthritis Treatment

You’re looking at a 300W far-infrared source with a 124mm head, and the key mechanism here is radiative heating in the 2-25 µm range that directly penetrates dermal and subdermal layers to a depth of about 3-5 mm. The CQ-29-1 is Class II medical device certified, so it’s been tested for electricla safety and thermal stability under continuous operation—something we’ve seen matter more for clinics running 8-hour shifts than for home users.

We usually ship these with a 1-year warranty, but the real life expectancy is closer to 3-5 years depending on how often you cycle the timer. The stand is adjustable, mobile, and weighs 13 kg, so it’s stable enough on linoleum but you’ll still want to lock the casters if you’re positioning it over a patient’s knee. 300W at 110V or 220V means you’re pulling about 2.7A or 1.36A respectively—check your local breaker rating before plugging in a bank of them. Most buyers go with the 110V version for US labs, but we’ve had European clinics order teh 220V model without issues.

It’s basically a TDP lamp, so the ceramic element is coated with a proprietary mineral mix that emits far-infrared when heated to the 300-400°C range—this isn’t UV or visible light, so no risk of photokeratitis or skin burns if you maintain the recommended 20-30 cm distance. The timer is mechanical, not digital, so you’ll hear a quiet click when it cycles off (usually 15, 30, or 60 minutes). We don’t recommend using it for acute injuries with open wounds because the heat can exacerbate edema in the first 48 hours.

One detail a buyer might not think to ask: the head doesn’t swivel 360°, it tilts about 180° vertically, so you can’t point it straight down at a supine patient’s back without adjusting the stand. That’s a limitation, but it’s fine for seated or side-lying positions. The carton packaing is 50×40×15 cm, so it fits standard freight boxes, though we usually have stock but confirm lead time for bulk orders over 50 units or so.

124mm head size gives a treatment area roughly 10-12 cm in diameter at the recommended distance—better than a 100W desk lamp for joint pain because penetration depth is actually tied to wavelength, not just power. CE certifcation covers the 2014/53/EU directive for medical devices, so you’ll get a COA with each unit, but the TDS is availble on request for the ceramic coating composition.
