Philips 36w TL-D U Form lamp questions « on: December 11, 2021, 11:20:12 PM » Author: WorldwideHIDCollectorUSA
When trying to search for European fluorescent tubes to add to my collection, I have noticed that some German wholesalers have these U-shaped T8 fluorescent tubes known as the TL-D U form tubes which are made by Philips. Do the Philips TL-D U Form 36w T8 fluorescent tubes have the exact same leg spacing as the North American F40T12U3 tubes and can they fit in North American F40T12U3 fixtures provided that I convert them to preheat and replace the terry clips with smaller ones to accommodate these T8 u bend tubes? Here is a leaflet with some information about Philips' TL-D 36w U Form tubes: https://www.lighting.philips.com/api/assets/v1/file/PhilipsLighting/content/fp928038584002-pss-global/ADAM-20151211092303018%40en_AA.pdf

Someone from North America should confirm this but I think the U-bents they use over there has wider leg spacing. I think it's 6 inch or something.

In North America, we also have U bend lamps with a 3 inch leg spacing too, but they are less common nowadays. As of now, the 6 inch leg spacing lamps are still in production. I was wondering whether the Philips TL-D 36w U form tubes had a 3 inch leg spacing too or whether the leg spacing was different due to European countries using the metric system and the US still using the imperial system.
