I want to buy and use some 54W T5 lamps. I have found some ballasts in a nearby shop. I have the following questions:
One of them advises 1x110W T10/T12 or 1X85W T12. Can I use it on two 54W T5 lamps? In general, can we use ballasts for T12 - for example - on T5's - considering the wattage matches?
Some of them are advised for T5/T8 lamps, others are for TL5 lamps. Is there any difference?
Suppose I have a 54W lamp, can I use - for example - two ballasts of 30W and 24W? That is: Can we combine lower wattage ballasts in some way such that it could power a higher wattage lamp?
Some of them are even advised only as 1x54W, without the Tn indicator. Can I use them on T5's?
Can I use ballasts of one manufacturer with lamps from another manufacturer?
There was a very cheap ballast for two 54W T5s and one (more expensive) for just one T5. Is it possible that this single lamp ballast will result in more light output?
If it is helpful, below there is a photo of the ballasts I found more promising for my purpose. Perhaps these questions are extremely common, but the seller didn't look to know about it and when I Googled a bit, there was a lot of doubt.
