Quasar Science LED tube lights with 3200 lumens, CRI >95, stepless dimming and bi-color capability (3000K–4300K), replacing traditional Kino Flo fluorescent fixtures.
Technical Details
The Quasar R-LED operates with a color temperature of either 3000K (Tungsten), 4300K (Daylight), or as a bi-color version with stepless adjustment between these two values. The light output for the 4-foot version is approximately 3200 lumens at full power, with a CRI (Color Rendering Index) consistently above 95. The tubes can be dimmed via DMX512, wireless apps, or manual controls, remaining flicker-free even at 1% brightness. An integrated power supply eliminates external ballasts, and the operating voltage is 100-240V AC.
History & Development
Quasar Science introduced the R-LED series in 2015 as a direct response to the demand for LED alternatives to fluorescent tubes. Founder Michael Cinquino developed the technology after years of criticism of traditional Kino Flo systems due to their flicker and limited dimming capabilities. The bi-color version followed in 2017, and wireless DMX integration in 2019. The latest generation from 2022 offers advanced spectral tuning features and plus/minus green correction.
Practical Use in Film
In productions like "The Mandalorian" or "Euphoria," Quasar R-LEDs replace classic Kino Flos as soft light sources for interviews, beauty shots, or as eye lights. Gaffers often use them in 4- or 6-bank configurations for large-area, soft illumination. Their instant full power output without warm-up time makes them ideal for quick setups. The higher initial cost and heat generation at full load, requiring active cooling, remain drawbacks.
Comparison & Alternatives
Compared to classic Kino Flo fluorescent tubes, Quasar R-LEDs offer stepless dimming and color temperature adjustment without loss of output. Competing LED tubes like Astera Titan Tubes focus more on RGB effects, while Digital Sputnik DS-Tubes prioritize higher light output. Modern alternatives include large LED panels like Gemini 2x1 or SkyPanels, which, however, cannot replicate the characteristic linear light fall-off of the tube form factor.
