i use lightforce lance 140 plenty of shine for the land i lamp on.although i find them very over priced in ire you are looking 100 euro.and at that you are paying for quality which you are and are not getting. the beam is the best on the market i think nice and tidy and can be adjusted plus great distance on the other hand they are very fragile in the connections i have my one best part of four years now and i have rewired it twice and put in one new bulb which isnt alot.and the other thing that really bugs me about it is that you can not get flip up filters for them and it is just impossible
