LED & Fluorescent Video Lighting

Video lighting fittings from datavisionWe can supply video lighting from the Datavision range including models using fluorescent and LED sources. LED lighting is probably the technology of the future, in that it's lighter, more robust and far more energy efficient than traditional tungsten lighting. The high efficiency has two benefits, the first being that little heat is generated (because more of the energy is emitted as light), and the second advantage over tungsten is that battery operation is more of a viable option, even for larger lights that would traditionally have required mains powering. LED 600 video light, equivalent to a RedHead but uses just 36WA light like the LED 600 (pictured right) gives about the same output as a 800W "Red Head", but draws just 36W, about the same as a large shoulder-mount camera, and can be run from a V-Lock camera battery for quite a reasonable length of time. A further advantage of the low DC power consumption is that LED lights are easily dimmed, and most units include a built-in dimmer.

Fluorescent video lights are available with 2, 4 or 6 55W PLL tubesFluorescent lighting is also significantly more efficient than traditional tungsten, with typically over three times the light output for the same power consumption, although the high voltages required to drive the tubes (compared to that required by LEDs) make mains powering the preferred option. That higher efficiency also makes them much cooler in operation than conventional tungsten lighting. In addition, tubes are available in different colour temperatures, making it easier to match daylight or tungsten lighting without the use of additional light-reducing colour correction filters. At present, fluorescent lighting is a cheaper option than LEDs, and the tubes are relatively cheap and easy to replace should the need arise. For video work, fluorescent light fittings are fitted with high-frequency electronic ballasts, to reduce weight and avoid the audible buzzing that mechanical ballasts can emit and, crucially, avoid any flicker that can occur when the light is driven by a frequency close to the effective shutter speed of a film or video camera.

Some, but not all, electronic ballasts on fluorescent lights include dimming controls, but it is possible to replace non-dimming ballasts with versions that include a dimming option.

Martin Kay offers help and advice on audio, video & computer problems
" I've been a regular contributor to user groups and technical forums for the last 20 years or so, and have written hundreds of posts offering advice and information on a whole range of computer, audio & video production topics."

What we're about . . .      ZEN is not a traditional Audio-Visual dealer who started selling computers, nor is it a computer shop that also sells video editing systems. You won't get any salesmen giving you the "hard-sell" when you call, just straightforward advice and information - which for some callers is the knowledge that they don't need to buy whatever it is they thought they needed! Above all you'll be dealing with someone with a wide range of experience and knowledge of both PCs and video production. We're not the biggest, nor necessarily the cheapest, but we are one of the longest established computer/video specialists in the UK.

Company history . . .      ZEN was started in the 1980s by Martin Kay, then working for ITV at Granada's Manchester studios, who built his first 6502-based computer in 1979 from an Ohio Scientific kit, bought in the USA whilst working as a Sound Recordist on a film shoot for World In Action. With the advent of the Amiga, which could be gen-locked to a video source, Martin started writing a variety of video-related software. This included subtitling & tele-prompting, ident clocks, scoring software for sports & gameshows, and specialist software to mimic other computer displays for use in TV film dramas like Cracker, Prime Suspect and A Touch of Frost. Martin left Granada in 1993 to concentrate on his computer-video activities with ZEN, following a natural path into non-linear editing systems, now the main focus of the business, although he still maintains an active interest in video production.
