1W 7000K 70LM White LED Emitter Metal Plate with Cover (3.5V)

Pros: Really inexpensive, seems to soldered well and when put three off this on bike with reflector (sku 01916) and driver (sku 13557) its more than you need.

Cons: none, I think.

Other: Good product for beginners to blow off without hard feelings but still good enough to give great light.
Lenses was leftover for my use but can be used with bare emitter and normal led.

Pros: Very small and versatile LED & PCB. Good even light output when used with the included lens assembly. Easy to solder and mount with the lens assembly clamping the LED PCB in place. All the LEDs supplied in my order matched output power, light spread and colour value making them ideal to be used together.

Cons: The lens may crack if overtightened. Do not over torque when installing.

Other: I would recommend this great little LED PCB and LENS set, I am thinking of using my next order for some floor level deck lighting.
