To be honest the twin Lumi’s IME are overkill. The Spot lamp helmet mounted is more, more than enough and has a perfect lightspread for single lamp use.
The Lumi headlamps are nice, neat and quite small. The toggle switch is a bit small. There are various modes operated by the single switch which works ok, but a simple high/low would have been prefered for me.
The lights are nice, but £400+ is too expensive for what is on offer with the twin kit, where as £250 is more realistic and bearable for the single lamp kit and is a great package compared to the likes of ayup, Hope, Exposure etc.
