I was going to suggest a 10A or 16A relay would be best and based on your
c=
alculations, that would be more than enough to keep it working for a long
t=
ime.

Simon,

70W fluorescent draws approx. 85W of inductive load.

As a rule of thumb you should multiply this by 10 for initial current draw
=
(more for switch off spike)

So for two lamps that=E2=80=99s over 7 amps, and the 5 amp rating on the
re=
lays is for a purely resistive load.

They=E2=80=99re over their current limit, that=E2=80=99s why they work for
=
a while and then eventually start to weld together.

HTH,

Simon
