New to the forum, thank you for having me!
I’ve been in search of a high CRI bulb that won’t break the bank, as bright as possible for a dark living room, in the 4000-5000 Kelvin range to use during the day. I use 2700 K smaller lamps in the evenings. I ran across a couple of decent options, but I found a Philips bulb that sounds very appealing. The price is not outrageous at about $6/bulb, 1600 lumens, I actually saw it on the shelf at the local Home Depot, and the 5000 K version has a 94 R9 according to the Energy Star test!
My question is regarding the spectrum in their spec sheet. All the different temps of this bulb have these unusually high spikes in the 600-630 nm range. What is the reason for this? Also, does it indicate a lower quality light bulb, and more importantly, can it be possibly damaging to eyesight negating the reasons I am seeking out a cool color, high CRI bulb? Sorry, I am a lighting newbie, hopefully my questions are not too silly.
