Woooo it’s bright. I reckon Light & Motion’s new LED Seca is way brighter than the old HID unit. Compared with the benchmark Lumicycle HID the L&M one just didn’t look as bright, it was good but seemed slightly to lack power.

The Seca however actually seems to put the Lumi in the shade a bit, especially at close range (up to 15m or so). At long range, ie when you shine it on the next hill across the valley, the Lumi again seems brighter. When riding there is a big, wide pool of evenly spread light easily sufficient for most riding. I haven’t tried it at high speed yet but am optimistic it will be good.

Other advantages include:

• It’s probably more robust than an HID bulb
• You can turn it on and off whenever you feel like it
• The heatsink gets hot enough to warm your hands on
