I've been using the HELIOS-300 for a while and figured I'd share some impressions since I've been getting more interested in red light therapy.

It's a relatively compact panel (15" × 8.7") but it's surprisingly powerful for its size. It uses **660nm red light and 850nm near-infrared (NIR)**, with 91 LEDs and a claimed irradiance of up to **163 mW/cm² at 6 inches**.

A few things I like about it:

* You can run the red and NIR lights independently or together
* Adjustable 10–30 minute timer
* 10Hz and 40Hz modes
* Comes with protective goggles, mounting hardware, remote and cables
* 3-year warranty
* Rated LED lifespan of 100,000 hours
* Actual power consumption is around 135W

I've mainly been using it for targeted areas rather than trying to cover my whole body. The compact size actually makes that pretty convenient — face, shoulders, knees, etc.

I'm still forming an opinion on the longer-term benefits, but the build quality and intensity have impressed me so far.

Some things I would've liked different:

* Longer power cord
* A better stand for easy positioning
* A bit cheaper price would've been nice

Anyone else here using a red light panel? I'm particularly interested in what people are using it for and how long it took before they noticed a difference.
