If anyone wants to see a video on DIY PCB making then look here.

Obv they are plugging their own products but some good tips.
Obv times are different for your own chemicals etc.

Obv there is silly music in the background.
Not so obv was a little info about UV tube output warm vs cold.
(I aways run them for 5 mins first anyway)
(I will make a prediction....)

Yes the video is quite informative.

All fluorescent type lamps take some minutes to achieve maxximum output illumination level. Evenb a standard fluro creates harmful radioation. It is the phosphors on the inside of the tube which convert the radiation into safe visible light. but it takes a while for the phosphor coating the become fully "excited".

If you turn a fluro off in a dark/black room you will see the tube still glows for a while as the remaining energy in the phospors dissipates.
