Hi
I’ve got a set of filament lamp Christmas lights, which I think is quite old.
It is a set of 80 lights, and the lamps are rated at 2.4V, 0.29W, 120mA.
The transformer is rated 24V(AC), 0.7A, 16.8VA.
It had 8 ballast lamps installed, so I assume 1 ballast lamp for a string of 9 normal lamps. However I don’t really like how the strings of 9 lamps flash on and off randomly, so I have replaced all the ballast lamps with normal lamps of the same rating as the others.
However, I thought this might overload the transformer because 80 x 0.29W = 23.2W, which is more than the rating of the transformer- 16.8VA( which I think is the same as 16.8W??).
So my question is: will this overload the transformer?
If so, would it be ok to only put in 55 lamps, to give a wattage of 15.95W, which is under the VA rating of the transformer?
Thanks for any replies!
