Richard, considering the price and the impressive performance in the comparison test I am tempted also to order and try your choice (LHD for Germany). 255 GBP a pair sounds much more attractive than 880€ a pair of Nolden.
In the product description for using in a Defender the below quoted advice is written on the powerfulUK site concerning the HL051:
„...We recommend using our open back headlight bowls when fitting these headlights as these LED headlights are sealed and run brighter the cooler they are. ( Search our other items for part number "HLB194" )...“
I guess the Morgan does not need a bowl at all because the lamp housing is sealed anyway? But does the sealed lamp housing of the Morgans on the other side could let the LEDs become too hot?
