When photographing in a studio environment, correct colour reproduction is important. To ensure correct color reproduction it is recommended to use the preset white balance option to provide the correct white balance for the light source being used.

Nikon provide the following advice. - When taking pictures of subjects that are illuminated with fluorescent light using a digital camera it is possible that variations in white balance from image to image can occur. As a result, the overall colour cast of the photograph can change depending on the exact instant that the shutter is released even thought the lighting conditions are constant.

The reason for this phenomenon is that the colour temperature of the light source changes during the power cycle. For normal AC lighting systems, the power goes from full to zero 100 times per second according to the variation in voltage.

Incandescent lighting has a high thermal capacity (the filament remains hot) so the temperature and colour remain relatively constant. Fluorescent lighting however uses a different method of illumination and the colour will change from instant to instant.

Our eyes do not detect this change as it happens too fast for us to recognize. However, the camera is able to capture an instant in time that the eye cannot, and when a picture is taken with a fast shutter speed these variations become noticeable.

The phenomenon therefore occurs when the shutter speed is comparatively faster than the frequency of the AC power source to the light. The solution with low energy lamps is to use low shutter speeds so that the complete cycle is caprured

• Daylight 150W
• 30W Low Energy Lamp
• Low Heat
• Colour Temperature 6500K = Daylight
• Daylight Spiral Low Energy 30W BC and ES Lamp Base available

• Daylight 75W **
• 25W Low Energy Lamp
• Low Heat
• Colour Temperature 6500K = Daylight
• Daylight Spiral Low Energy 25W BC22 - BC Lamp

• Daylight 40W **
• 11W Low Energy Lamp
• Low Heat
• Colour Temperature 6500K = Daylight
• Daylight Spiral Low Energy 11W BC22 - BC Lamp

** The lamps are equivalent to
11W - 550 Lumens - 55W
20W - 1000 Lumens - 100w
25W - 1250 Lumens - 125w

The new EU rulings for packaging state that lamps that fall between 970 and 1397 Lumens may only show on the packaging that they are equivalent to 75W. For 432-740 lumens packaging may only show 40W
