These curious and mesmerising instruments measure the power of electromagnetic radiation. Made from a glass bulb with much of the air removed to form a partial vacuum, inside is a set of fine metal vanes, each with one dark and one light side, mounted on a spindle. The vanes rotate, as if by magic, when exposed to sunlight, artificial light, or infrared radiation (even the heat of a hand nearby can be enough) – the more intense the light, the faster the rotation.
We offer three delivery options:
Standard UK Delivery: £4.99.On this service, goods will usually arrive within 14 days of your order reaching us, and often in less than 10. (Please remember that if you posted your order it may have taken up to five days to get here).
Three-day Delivery: £6.99.This is a three-working-day (not Saturday, Sunday, or Bank Holidays) service for UK mainland and Ulster addresses, provided that you order before 1pm. Orders received after 1pm will be processed on the next working day, so take one day longer to arrive. If you require an item to be personalised, your order will be delayed by one working day.
Express Delivery: £9.99.This is a next-working-day (not Saturday, Sunday, or Bank Holidays) service for UK mainland and Ulster addresses, provided that you order before 1pm. Orders received after 1pm will be processed on the next working day, so take one day longer to arrive. Service to Scotland, Northern Ireland, Isle of Wight and other UK Islands takes two days.
If you require an item to be personalised, your order will take an additional working day. Your package will arrive between 9am and 6pm (may be up to 8pm), and must be signed for on receipt, so please give an address where there will be somebody available to take delivery (perhaps a neighbour/friend, or your workplace if your employer permits this).
