Title: Viewing lights
Hi All
I have had donated to me a Just viewing light, of indeterminable age and model. It is a quite large overhead viewing light, which takes 60 inch tubes. I was also given with it a box of new graphiclite d50 tubes. I have replaced the tubes with the new ones, but still the colour temperature of this light is up around 5800k.
I was wondering if anyone has much experience in how viewing lights work, and what the problem could be. My theories thus far are:
Does it matter that it is a Just box, but I have graphiclite tubes in it? Should the brand of tubes match the manufacturer, or should it not make a difference considering they are both colour correct tubes? As far as the actual tubes are concerned, are they the only thing that affects colour temperature, or does the actual electrical appliance’s power output also affect the resulting colour temperature (hence my theory about matching tube & light manufacturer)?
Does the height from the bench affect colour temperature? I am assuming that it would only affect illuminance levels. We have a number of GTI lights, which are performing well as far as illuminance & temperature are concerned, and this light has been hung at around the same specs as our GTI lights, except that it had to be brought further forward of the bench, as it throws the light back further.
Or do they just get to an age where they’re just past it & it’s time to throw them out?
Any suggestions would be greatly appreciated.
Thanks, Bee
