In article op.vr86trian5ksl5@richard, says...
The list of suitable lamp types is given on the page to which I linked
(e.g. 4-65W linear T5/T8/T12); there is no suggestion that they are
anything other than standard tubes. The only specific limitation
mentioned is that it is "only suitable for inductive circuits without
capacitors for serial compensation".


Did you read the bit about the guarantee not being valid if it's not
used daily?
