Using the VO2223A to switch a 230Vac LED lamp
Yes, the VO2223A can be used as a moderate current SSR for AC loads: It is a power Triac switch.

The VO2223 and VO2223A parts are in fact designed for switching power-line (up to 600 Volts) AC by low-voltage control signals such as from a microcontroller, with 5300 Volt isolation between the control and the output circuits.

The parts are rated for switching a 44 Watt load on 220 Volt mains lines, or a 22 Watt load on 110 Volt mains lines. 

If the LED used is in fact rated for 26 mA at 230 Volts (datasheet would help confirm), that is a power rating of just under 6 watts. It would thus be safe to operate up to 7 such lamps in parallel on each VO2223A part. 

Note that the datasheet derates the current capacity to approximately 0.3 Amperes at 80 degrees C, from the nominal 1 Ampere at 25 degrees. This is not a problem in the stated application, as 7 of the LED lamps would draw approximately 0.182 Amperes altogether.
