Review on 🌀 OttLite 15ED420 Natural Swirling Screw by Gary Davis

Brightness, contrast and CRI (color rendering index) come very close to natural daylight. This makes the application very pleasant and convenient. I think around 3500-4000K. I don't know exactly, I'll take a look. This lightbulb is a godsend when most energy-saving lightbulbs cause eye pain, blurred vision or migraines. Since most incandescent bulbs are becoming illegal to sell, I'm looking for artificial lighting that doesn't give me a headache and doesn't make my vision virtually useless. It doesn't flicker or cause flickering (like 99% of LED lights), especially when you're trying to read or otherwise move your eyes. It doesn't have the poor and faded color rendering of most LED and fluorescent lamps. It doesn't have bad brightness and contrast. With this light, you can accurately assess an infant's well-being or observe a person's skin condition, whether they are pale or healthy, which is so important for first aid and early intervention. You can also fine-tune the color at night. It is 98% as good as perfect indirect daylight. Brightness and contrast as well as CRI are so close to natural light. It corresponds to the color temperature of indirect sunlight in the middle of the morning on a clear, sunny day. Not blue per se, but definitely not yellow or warm. I find it invigorating and stimulating. It's great to use on my desk and workbench. So I try not to leave it on after 9pm unless I need to stay alert and do some work. One downside: They don't come in lower wattage/lumens. It would be nice to have bulbs that emit less light. it would be nice to have a color temperature around 2400 or 2700K with the same wide color gamut, if that's even possible. Another downside: if someone in your home has lupus, the fluorescent lights can cause a flare-up and leave the person with symptoms typical of exposure to too much sunlight. I verified that the bulb was not flashing or pulsing by videotaping the reflected light from the bulb (rather than the bulb itself) in slow motion. This is extremely stable lighting. I wish regulators would take disability access into account when banning incandescent bulbs. People with vision problems, migraines, epilepsy, autoimmune diseases, dyslexia, etc. are best suited for incandescent lamps. There are other, much more effective ways to save energy than doing without safe lighting.
