Question 1

is this bulb made by Satco?

Accepted Answer

I bought 6 F8T5 halophosphor long tubes for little over $1.00 each.They are made by "CH LIGHTING" using the rare earth halophosphor powder on their line of products.They advertise it as of stable quality, reliable, long life span and energy saving (8 W)  It has a 3000K degree color (closer to tungsten than fluorescent) which is comfortable to eyes.  A day-light tube has close to 5000K or 6000K degrees which it will be hard on my eyes.  I think they are good bulbs, I am using one only at this time.  However, I have a problem: after 2 months the bulb doesn't start completely at the first start and flickers a bit.  I decided to turn the bulb OFF and ON again and the bulb works just fine, pleasant color and I leave it on even in the day-light.  You know, living in Seattle is so dark in the winter that we are moving like zombies and you need to have some light on most of the time.   I am using also an old light appliance I found in the basement 25 years ago so I don't know if this bulb has a slight issue or my old appliance/starter has an issue being old.  I will test another bulb next month.  But I encourage you to buy it, the price is right and I am sure it is going to work.  What I like is that it doesn't create electromagnetic fields interfering with my portable radios or phone.

Question 2

How is the 12" measured?

Accepted Answer

It includes the prongs and measure 11 and 7/8's.  Working well for under counter lighting.

Question 3

what ballast do these bulbs require?

Accepted Answer

these bulbs are 12volt for rv fixtures

Question 4

Bought a ge f8t5/cw and it is literally 1/4" longer than the one that blew.  anyone know which brand would be shorter?

Accepted Answer

I was unable to use these as they did not fix my fixture also.  The product I bought that works in my fixture is a Sylvania bulb made for my fixture.  They are a little shorter but the main thing is at the end of each bulb is a rounded rectangle.  When putting in the fixture you need to rotate them and they snap in.  I had some problems trying to find what worked in my fixture.  I ended up going to a lighting place in my area with a sample bulb and they took care of it immeadiately.
