## Questions & Answers

**Q: Is this bold bright enough to read by on your nightstand like maybe a 40 W bulb would?**
A: Yes. My mom used one for reading - she is over 70. I would estimate the light is equal to between a 40W and 60W bulb. I use only one bulb to light everything in my great room (living room and dining room) and kitchen area at night. It's enough for everything I need to do.

**Q: How is this different from an ordinary light bulb with an orange coating that filters out blue light?**
A: Unlike many simply filtered lights the initial spectrum of the bulb is also adjusted so the while some of the blue is filtered what remains is a light still capable of rendering color sufficiently for our perception.

**Q: I work night's and have trouble sleeping during the day!  Would it help me?**
A: It has definitely helped me with being able to get to sleep when I want to. You have to make sure you don't have other sources of blue light as well (cell phone, monitor, TV, etc...).

**Q: Is this bulb dimmable?**
A: Yes, it's fully dimmable.

## Customer Reviews

### ⭐⭐⭐⭐⭐ No side effects & getting my life back
*by S***C on October 31, 2015*

This is a convenient way to convert my table light to help me with my sleep disorder.Well worth the price, fits a regular size base. Allows for brain to get the correct signal and assist with resetting your internal clock. This is very important as many systems rest when you sleep, your body has to replenish & reset hormones, melatonin, neurological, pain receptors etc. just to name a few, but also helps prevent premature aging, wrinkles, helps with obesity (yes, you have to not overeat) yet, brain receptors of being full need rest.Think of it like this:, when a baby born, they sleep a lot for a few days, and many have nights and days confused when you get them home (hospital nursery lights on 24 x 7). As a mother you try to get them slowly on a regular & normal schedule (awake during day / sleep at night ) same principle made simple. The reason why adults have issues are, location of where they live, life stress, jobs (shift work that rotates ), & poor habits over the years along with age, medication so forth. Your body's timer no longer works properly = needs resetting & some people require this daily assistance to keep it in proper alignment. I am one of those people.Now, some people have a system that is reversed from others =night owl's & that's just how they're made & have no issues. This is perfect economically for people who have difficulties falling asleep, and like me don't like the side effects! Prevents those, bulb lasts longer than a month as you only need to use about 30 minutes a night. (Depending on your condition & your Dr. Order /Recommendation )NOT giving or Providing medical advice, just information related to MY PERSONAL medical situation & orders. Prior to this therapy, in 5 days, only had 8 hours of sleep.

### ⭐⭐⭐⭐ very nice and confortable light

I am not sure if it works, but the collor and it's light is pretty confortable during the night

### ⭐⭐⭐ Hasn't seemed to help with my sleep though but I'm sure it's better than the other light I had by my bed ...
*by L***J on June 3, 2015*

Light is brighter than I thought it would be, but a soft bright. Hasn't seemed to help with my sleep though but I'm sure it's better than the other light I had by my bed side.
