This ribbed single Seoul P7 LED head unit from Leddite is comparable in power to other lights at double the price.
There are some ring marks in the peripheral but the beam is good enough to be able to ride hard on challenging terrain. Its weight is good and battery life is ample.
The single click backlit switch and O-ring handlebar mount are easy to use, and the connectors and head unit are well sealed. Although it gets very hot, we’ve not had any issues as a result.
They cost $80 direct from the Far East under the name Magicshine but Leddite add a UK charger, a guarantee and the convenience of buying through your local shop while keeping it a total bargain.
