What is the difference between Kino Flos and store bought fluorescent's?
Kino Flo True Match® lamps are the only High Output (HO) fluorescentlamps designed to correspond to the spectral sensitivity of film anddigital imaging. In 1995 Kino Flo was awarded an Academy Award forTechnical Achievement for its unique lamp engineering and fixturedesigns.
Is there a color difference between Kino Flo lamps operating in an architectural fixture vs. a Kino Flo fixture?
Kino Flo’s 4ft and 2ft T12 800ma lamps can be used in architecturalfixtures. Due to the lower operating currents of architecturalfixtures, the Kino Flo lamps may appear slightly more magenta to theeye than the same lamps in Kino Flo fixtures. However, on film, videoor digital the light quality of the two fixture types matches.
What is the difference between single pin lamps and double pin lamps?
Single pin lamps are referred to as Slimline fluorescent's. Slimlinelamps will not operate on Kino Flo HO ballasts. Most double pin(bi-pin) lamps will operate on Kino Flo ballasts. However, Kino Flo HOballasts will shorten the life span of store bought bi-pin lamps.
Do Kino Flo lamps operate in architectural High Output (HO) fixtures?
Architectural HO fixtures can range in lengths of 4ft, 6ft and 8ft.They use a lamp that has a double recessed bi-pin end cap. It lookssimilar to a single pin lamp but the pin is hollow and oval shaped.Kino Flo 6ft and 8ft lamps can be modified with an accessory DoubleRecessed End Cap that slides over the lamps normal medium bi-pins.However, Kino Flo 4ft lamps cannot be modified this way becausearchitectural 4ft HO lamps are three inches shorter.
Why do some lamps in a fixture seem slightly different?
Slightvariations in appearance are common from lamp to lamp. The age of alamp and the batch number can account for variations. When evaluatingcolor temperature, position the color meter at least 24 inches (.5meter) from the fixture or lamp. Holding the meter too close may resultin inaccurate readings.
What does High Output (HO) mean?
Why do my lamps read green on my color meter?
Tip: If a 4ft lamp is operating too hot and the color is shifting green,move the select switch to Std (or 2ft). This will reduce the lampcurrent and drop the green spike.
Dimming vs. SwitchingAll fluorescent lamps will drift toward magenta when dimmed. The shiftis continual as the lamp physically cools. Kino Flo recommends onlydimming one f-stop to ensure good color. The Select Ballast serieschanges light levels without affecting color balance by switching lampson and off, and by using the 2ft/4ft select switch, which adjusts thelamps by 1/2 f-stop.
How do color meters read fluorescent lamps ?
Unfortunately,color meters available to cinematographers are far from beingscientifically accurate when reading fluorescent's. They act as a greatcomparative tool to determine differences between twogivenlight sources but are inadequate in providing definitive data. You willrarely find two color meters, even if they are the same make and model,that provide equal data. Results between meters may be similar but notidentical.
