I’m new to this forum (and lighting in general), and I’m looking for LED lights with the following requirements:
Replicates daylight very well in SPD (I think this naturally correlates with high CRI?)
Doesn’t have too high of a spike in HEV blue light, for eye health purposes. (I know that this topic is controversial and studies are not conclusive, but I’d like to err on the side of caution.)
Has high lumens/$ ratio, since I’d like to possibly buy 10-20 of these bulbs (along with splitters) to get the intensity of sunlight in the home (kind of like anti-SAD lighting).
If this question has already been answered elsewhere in the forum, please let me know.
I did find this review by @maukka that has a high opinion of Waveform Home/Daylight 4000k/5000k bulbs. Is there anything better than this?
There is also SunLike which is run by a member of this forum going by that username. maukka has reviews of some of his products up as well.
If you do go with Waveform make sure you pick the flicker-free version - I also have of theirs that isn’t and the flicker can be very noticeable (it’s relegated to a less-used fixture now).
He also sells individual SMDs & COBs, as well as PCBs in a number of different shapes. I’d love to see him produce a flexible strip like this:
But in any case, yes I’m going to find a combination of the above that works for this application. The thing that sent me down this path years ago was the youtube videos by DIYPerks, making DIY LED panels.
Great questions. You’re correct that the bar you linked to could be helpful by itself. I’m looking to spread out the light source(s) to simulate a window and/or skylight, and I’d like to be able to simulate not just daylight, but a range of color temps.
I mapped out the concept in a post from a while back. Warning, it’s a bit wordy :innocent:
