The Quasar Tubes Q-LED X CrossFade Linear Lamp 4ft is a Variable Color LED replacement for a T12 4' fluorescent lamps. These 50 watt tubes produce 90 lumens per watt! Quasar lamps are dimmable, flicker free and 25,000 hr average life. Best of all the Quasar Tubes are rugged, built with aluminum frame and plastic front diffuser. They can operate as a single tube or ganged together for a large light source. A really neat tool is the optional Modern Studio Fluorescent Lamp Holder. Holds a single tube and has a 5/8" diameter baby pin for mounting in a c-stand.
Featuring a CRI of 95+ and no green or magenta spike. The X Crossfade lamps have a wheel at the end of the unit to scroll to the desired setting color temperature from Tungsten 2000K to Daylight 6000K. 120 volt AC power is required at just one end of the tube, reducing cabling needs. Each lamp ships with (2) Q Boots and (1) Quasar Grounded Female Tri-Pin to Grounded Male Plug.
Given the inevitable fact that all LEDs eventually "burnout" after lengthy use as the phosphorus fades, our LED boards are completely replaceable just like a light bulb.
This allows the Driver and Heat Sink to last well beyond the life of the Light Emitting Diodes. Once the CRI drops, just slap in a new LED board.
Upgrades are also possible as advancements are made in the ratio of Lumens Per Watt, future LED boards will output more light utilizing the same driver and power supply.
Our Snap-In driver system makes maintenance quick and painless; allowing for a quick swap between 120vac and 240vac drivers. This also keeps entire systems from being "totaled" as when one simple malfunction would drag down the whole apparatus.
Increased durability was a result with a reduction in soldered and crimped terminals we are able to build incredibly tough and long lasting hardware for the rough conditions of professional lighting.
**A "Ghost Load" is traditionally an off camera light
used to draw additional power in order to balance
and stabilize a power supply.
In this case a small incandescent light bulb (around 15w) should be attached to the line to burn off any voltage leak from the dimmers.
