These are just to see some examples of different reds.
The top is US's BlazingRed, and I'd say is the brightest of these.
The middle is just something I got online. I'm not sure exactly what it is. Someone's own mod of a collectible. Not any of 'the other guys'.
The bottom is an US with QD that I put my own make of tri cree deep red.
The BR is still brighter, even though it's single LED. But I've seen some folks share their deep reds and I was curious. So, this is the result. I like the deep red, but I can see that it takes a tri with parallel wiring to get something reasonably bright. I was gonna make my own quad, but the only quads I could find were in series, so I thought tri in parallel would be comparable.
BR has some orange to it, but that adds brightness. Perhaps a triBR with a filter would come out like this TriDeepRed.
