Fluorescent Bulbs

Then we have fluorescent bulbs, which are the economy class of therapy bulbs. They're cheaper but emit a more diffused light, which can be less effective for therapeutic purposes. Plus, they don’t match the lifespan or the energy efficiency of their LED counterparts.


Comparing wavelengths and energy outputs

When it comes to RLT, it's not just about shining any red light on your skin. The wavelength and the amount of energy the bulb outputs are crucial. LEDs typically emit light at a wavelength of 630-660nm, hitting that sweet spot for therapeutic benefits. Incandescent and halogen bulbs scatter their wavelengths more, reducing their therapeutic effectiveness. Fluorescent bulbs can emit at useful wavelengths, but their lower energy output makes them less effective for therapy.
