The listing image shows a light that produces a strong, intense purple glow. Fantastic, I thought, because that's exactly what I need. , a washed out pastel purple glow that was so disappointing I thought the first two bulbs I ordered must have been from a defective batch. But when I sent them back for exchange I got the same result. The company's green flame light is excellent in comparison. , and their blue flame light is pretty good too. But try something else if you want to render images with rich purple light, as it doesn't even come close.
