Hi Guys ! Not so much about Flightbadges , but a bit about light . As John write Daylight is the best to takes pics in . But sometimes like here in Norway we dont have any good Day/ Sunlight , It is possible to use fotolight ,but I often use lighttubes . Then it could be ok to now someting about lighttube codes . The code is always first how many Watt ( old T8 tubes 18 , 36, 58 watt ( 18mm thick ), newer T5 ( 13 mm thick ) tubes have 29 , 49 , 80 watt ) , then comes a / , and so 3 numbers . ( do not use tubes with only 2 numbers ) . First 800 series : first number indicate how good the coulor-representation /- reflection ( dont find the correct word in my Wordbook )is compared with sunlight , 8 in the codes means 80% coulor-representation of what You will se in sunlight . Two last number is Kelvin : 830 means 80% of Colour- , and 3000 Kelvin ( yellow - white light ) . 840 is 4000 Kelvin . Thes higher Kelvin is , light getting more and more white . I use 840 tubes . You can also find 900 serie tubes , with 90% Colour-. , kelvin code is the same as one 800 series . And let the light be on about 5 minutes before start taking photos , tubes need some time to get warm and full light . I know Osram has come with 880 and 980 tubes this is extremlly white light . If You go to a shop and look a Tomato it looks very red and nice , if you take it out in daylight it looks different then it was inside the disc. The tube maker has made a spec. tubes for fruit- and meat discs . The light tubes is cheating you . A little bit outside the tema , but hope someone can have use of it . Jan Arne
