220V 80*120mm E27 40W G80 Spiral Edison Bulb

CFLs - An electric current flows between electrodes at each end of a tube containing gases. The reaction produces ultraviolet (UV) light and heat. The UV light is transformed into visible light when it strikes a phosphor coating on the inside of the bulb.

Available for outdoor use; just make sure the packaging indicates the bulb is rated for outdoor use.
May not hold up to the stress of power surges. So using them in areas such as workshops is not advisable.
If the outlet is wired for a dimmer or three-way bulb, make sure you purchase a CFL rated for the specific use.

LEDs - Use an electrical current passed through semiconductor material to illuminate the tiny light sources called LEDs.
The heat produced is absorbed into a heat sink, keeping the bulbs cool to the touch.

Available for outdoor use; just make sure the packaging indicates the bulb is rated for outdoor use.
Do not contribute to heat build up which helps save on air conditioning.
