One film with a normal fluorescent tube from the cheap DIY goes in the pants. Colors do not match, and it usually flickers. Better are the tubes with Ra = 98 and electronical driven, they are usually driven with 40 kHz, and even give the shutter 1 / 1000 or housing for installation. The coronation is then when the switching device has a dimmer, then the brightness can be well controlled and the colors remain almost stable.
Watch it, will not contain an RA value, hands off of the lights. Under RA 90-95, you can forget in Color Video .....
RA100 = Sonnenfarbspektrum

Phillips Light Color 11 and 13 .... 3200 and 5400th
Cost per piece scarce about 10 euros .... are offered for the terrarium to get at the hardware store.
RA values are standing on it only very small.

Antwort von Markus_Krippner:
Fluorescent tubes with good Ra (color rendering index) are called at Osram "Lumilux de Luxe" and of Philips' TL de Luxe ". They are recognized synonymous s.Ihrem 3-digit color code.
940 zb
The first digit stands for the color rendering index x10.
So 9x10 = Ra better than 90
The next two digits correspond to the color temperature x100.
So 40x100 = about 4000 Kelvin.
There are different color temperatures, but generally not the industry standard 3200 or 5600 Kelvin. But you can indeed hindrehen Not with correction for films. In contrast to the color rendering index! Which is firmly and can be corrected with ninth measure. So pay attention, "and guggn to the color code. Necessarily those with the "9" Buy s.Anfang.
Or buy one of course, the same official tubes zb Kinoflo. Since everything is true. Color performancealle over 90 And in 3200 or 5600 Kelvin color temperature. But, unfortunately, not quite cheap.

Antwort von MK:
The tubes with electronic ballast out of the house called T5 and running with 40kHz and are synonymous with the same wattage more light output than T8 tubes.
Light is the price difference is not all too great, the construction market, the T5 Choice is usually fairly limited, however, so better order.
