Overall, what are the benefits and drawbacks of HW-CFLs?
High-wattage compact fluorescent lamps (HW-CFL) offer a number of benefits, but present some drawbacks as well.
Among the benefits:
Drawbacks and concerns:
- HW-CFLs are more suited optically for diffuse illumination rather than for directional lighting.
- Enclosed luminaires may overheat the ballast electronics of self-ballasted products.
- Many manufacturers recommend avoiding frequent switching; therefore, HW-CFLs may not be appropriate for use with occupancy sensors in some applications.
- HW-CFLs are large in size and may not fit within some luminaires.
- Due to complex shapes and difficult-to-clean surfaces, dirt depreciation may be greater with HW-CFLs than with other light sources.
- Relamping may be awkward; many lamps are too fragile to be held by the glass end and must be handled by only the base.
- Large size increases storage space requirements.
