230v is a standard also in Spain, France, Germany and almost every other European countries
You could take the Agromax PureUV bulbs. They are T5's(2ft/24w or 4ft/54w) and you could use the Philips HF-Regulator 124TLS220-240, which is a 0-10v dimmable T5HO ballast for 24w T5 bulbs. Its also available for 2 bulbs in this case it's called HF-R 224TLS 220-240 and as the name suggests its made for 220-240vac and dimmable between 1-100%.
Such a 24w bulb costs only ~20€, a 5-pack T5 sockets costs 1€(e3ay) and ballast can be between 20 and 40€ depending on which one you want. And for dimming you could use Osrams Pico dimmer which is made T5/T8 dimming or any other 0/1-10v dimmer. These ballasts are also available with dali dimming option, btw.
From UVB intensity they are comparable but they need an additional reflector with metallic surface. No built-in reflector...
