@Joseph: Yes. Can you send us a message if you decide you want this for sure and we will make a note.
@Kareemo. The phosphors used for amber are a bit less efficient than white. These are the most efficient amber LEDs available though. Further tests will be needed, but the Amber FlarePro will be about 750 peak/ 550 continuous. To the eye, as a "be seen light", it appears possibly more intense (or the same) compared to the white though due to the color. Eyes perceive certain wavelengths differently in intensity.
White Lumens: 950 peak/ 700 continuous
What is the Amber Lumens?
I pledged for a red and white. Can I now choose red and amber?
