Anybody using dimmable energy bulbs with their LC2. Can you recommend a make and high street store where I can buy some?

Bought these

but an Amazon review says, "These bulbs ONLY work with light switches with LOW LOAD LIMITS !!! of 20 Watts or less, otherwise they will burn out almost intantly."

The LC2 manual says, "The LC 2 is designed for a mains voltage of 220–240 V (AC) 50 Hz, and a load power of 40–300 W."

What do you think?

Source. "Minimum load requirements (This energy saving light bulb is rated to 20W), must be met for this energy saving light bulb to work. For example if the dimmer has a minimum load of 60w you must use 3 of these energy saving light bulbs."

Cancelled my order. More research needed. Saving energy really shouldn't be this difficult.
