Hello, yes this bulb is 580mm from end of pin to end of pin. If you want more information on measuring a fluorescent bulb, check out our guide: https://www.electricalworld.com/en/Helping-You-Choose-a-T4T5T8-Bulb/cc-59.aspx thanks

Hello, thanks for the question. It may fit, however, we would recommend trying to match the previous bulb measurements.

Thanks for your question - Our T4 tubes are different length for different wattages. The wicks code you are referencing states 10w but the tube is 20w. I cannot find the model you have provided on wickes site, so I cannot confirm if the tubes are the same length. However you cannot put a 20w lamp into 10w fitting.

Hello. My current lights use aurora AU-TT420S bulbs, which seem to be obsolete. Is this one an exact equivalent in terms of length? Thanks

Hello Paul, the best way to make sure that this will be a suitable replacement is to measure the tube that you currently have. There is a lot of variation in T4 tube lengths, so take the measurement either pin-to-pin or cap-to-cap, and then use that measurement to find a replacement. A good starting point for a 20W T4 tube might be https://www.electricalworld.com/SearchResults.aspx?Search=t4&AttributeValueIDs=1404 - thank you for your enquiry.
