Dear Ilumi,
I saw your bulbs in this a website and i really like to get one but i dont know which is the best for me. I would like to use it in a 4mX4m room, in which the lamp is in the center about 2,5m up.( but maybe it will be in the corner in the same height). Which one would be the best, would brighten up the room, the small or the big. My other question, i have a samsung galaxy young 2 android 4.4 phone with bluetooth v4.x, screen resolution 320x480, can the i operate the bulb with this ( does your app support this screen resolution, bluetooth version) Looking forward to your answer, and i hope You can help me and i will be a happy costumer in the end.
Yorus Sincerely
ilumi

TatdanHi Tatdan!
To find out how many or what types of light bulbs are needed to light a space, you'll have to do just a bit of math. I recommend checking out a site like http://www.houseplanshelper.com/lighting-calculation.html for getting the exact number of lumens needed per room type. Then you divide the lumens needed by the lumen output of the bulb type you want to purchase, and that is the number of that type of bulb you need to install in the bedroom.
Based on the chart, your bedroom for ambient lighting would need 864 lumens, which is about the lumen output of one Small A21. For a good explanation of "lumens" versus "watts", check out our blog article here: http://bit.ly/1e5zOPO
Keep in mind that the Small A21 bulb is best used in table lamps, floor lamps, and ceiling fans and the PAR30 is best for recessed or canned lights in the ceiling, so you'll need to select based on what type of lighting fixture you plan to use in your bedroom :)
I looked at the specs of the Samsung Galaxy Young 2, and I don't see anything that would indicate that this phone would be incompatible. We don't have this exact device for testing, but we do have several of the Samsung Galaxy series phones, which are compatible. If you have any issues, you can always reach out to our support team at support@ilumi.co and we'll get you fixed up :).
Let us know if we can help with anything else!
