Hi Paul, we are listening.
Your opinion and tips will be valued.
Yep. It depends on the perspective ;)
Hi Theuer, @see the extensive reply above, if you have any other question feel free to ask :)
Hi Paul, thank you for your suggestion on the video, we are shooting a better one.
- White LEDs are quite a delicate matter. They are blue diodes covered with patented phosphorus that convert part of that blue light into green, red and yellow one. The mixture gives out white light. Yes, indeed, there are a lot of minor producers with claimed 90+ CRI in every CCT possible, but we chose to stick with two of the most respected LED producers in the world, and they *certify* their minimum CRI with absolute seriousness. They offer 90+ CRI LEDs in selected bins, and the ones closest to the planckian locus (= closer to natural black-body light emission) fall into 3000K, 3500K and 4500K CCTs.
- No, they are not. Dimming leds is complicated: you can decrease their current, or make them blink so fast at full brightness they seem to dim (it’s called PWM). Also, dimming produces emitted color drift, because phosphorus response is not linear, and CRI wouldn’t be constant across the whole range. Moreover, dimming by PWM may pose issues when filming at high-fps, producing beatings / stripes you surely may have encountered when filming with neon lights. Given that, the best way to dim Relio is by placing a shading mask in front of it (with the included PMMA holder).
- No battery, it would last 10 minutes and degrade in 1 month because of heat. Relio has a MTBF of 50000 hours, no device with internal battery could have that durability estimation.
- Because we spent countless hours matching and calibrating TIR lenses, the beam is perfect, no spills and coronas on the side, it has high-efficiency, high-frequency step-down electronics and because Relio won’t fall apart in the first 10 minutes of use.
