You'd need a 4-pin 2G11 base LED tube. Google certainly seems to suggest they exist. I've no idea as to whether the Diva's ballast could drive them though.
Paul do you have a link for Pyrmid? I look and couldn't find the flos. Actually interested in replacing the tubes in my shop but if they made blax that would be fine too.
Thanks
Brian

Yes, Mactech. The former Bardwell McAllister. I have several of the lamps. The only problem is to dim them. It will require an analog dimmer. There are several Variacs for very cheap.
