It is UVA, but at the upper edge (385nm), and visible light is sometimes defined as 400-700nm, other times as 380-780nm. Not sure why. UVA goes all the way down to 320, but 380 is the neuropsin peak (OPN-5). The Chroma Trinity we are working on will be the everything combo light. Dr. Jack actually suggested we do the total combo a while ago and we held off due to trickiness with getting a switch for UVB, but we will have that.
