Hi, Im new to this forum but not new to lightsabers. Currently I only own one Saberforge lightsaber, a prodigal son in green. However my 2nd saber is on order and will be in red.
I fully expect the red to have a somewhat orange hue to it because every other saber Ive ever owned has been this way. Whether Ultrasabers, blazing red, custom sabers or master replicas or Hasbro sabers, all of them have been on the more orange side of red.
In my experience most red LED's have to be a compromise between color and brightness. The human eye does not see all colors at the same intensity. Different colors have a different apparent brightness. For instance if you put a 12W green Led side by side with a 12W red LED, running on the same exact power source at the same level of charge using identical blades, the green will appear brighter every time because green has more apparent brightness to the human eye than red does.
Red also happens to be the color with the longest visible wavelength. The closer you get to pure red the closer you get to the infrared spectrum which is invisible to the human eye. So in order to pump a pure red LED up to the apparent brightness of say green you need a lot more power than you would for the green LED to get the same apparent brightness.
The same holds true in audio. Bass frequencies require a lot more amplification to bring them to the same apparent volume as more treble frequencies.
Red is the visual equivalent of what bass is to audio.
I believe most red LED's are shifted away from what we would consider pure red to be able to achieve a more acceptable brightness while still being power efficient. A brightness to color compromise.
Ultimately I would rather have the red appear brighter even if slightly more orange than I would to have a dim, although pure red LED. Its personal opinion of course, but I believe that is the compromise you have to make with red.
Quite true. This is something you'll notice almost everywhere: stop lights, brake lights, power lights in small electronics, etc. There is definitely a compromise between brightness and wavelength- something current semiconductors are not able to overcome so well.
I'm actually running through some theoretical values to see what the potential brightness difference you would see in a 650nm red saber would be. I will probably report back at some point with what I find.
