E40 Lamp Holder

CFLs are the slightly cheaper alternative to T5 lighting. Not good for the environment because the electronic ballast is integrated with the tube and has to be discarded at the same time as the tube fails. Also the inferior geometry of CFL (internal tube) often means that more than 40% extra light output can be achieved by linear T5 of the same power rating. For example, the 144w EcoSlimLine Set will downlight the same area with as much useful light as any 220w CFL and the 96w EcoSlimLine Set will downlight a greater area with more useful light than any 125w CFL.
