    Involvement:Expert (understands the inner workings) - Ownership:1 week to 1 month

    Pros:

    -Cheap like everything on DX.
    -The total power of the LEDs in the lamp is actually 5 W. Surprisingly the item description is correct from this aspect.

    Cons:

    -Mechanical parts have less than poor quality.
    -After receiving the lamp, disassemble it and apply enough heat transfer gel between the heat sink-reflector and the reflector-PCB surfaces!

    OtherThoughts:

    LED:
    There are 10 pcs of 0.5 W SMD LED in the lamp soldered onto an Al core PCB. Check my pics. The PCB board of the LEDs warms up to 57 C° after 1 hour of operation.

    Heat sink:
    Made of aluminum. Warms up to 44 C° after 1 hour of operation on free air with 24 C° environmental temperature.

    Power supply:
    The high-frequency transformer is the hottest point, it heats up to 52C° after 1 hour of operation. The size and the design of the PCB seems to be appropriate to drive a 5 W LED. Check my pics.

    Bottomline:

    LED power is as advertised. Light amount is definitely less than 450 lm. Color temperature is around 3500 K as advertised.

    • Inside: 10 pcs of 0.5 W LEDs
    • disassembled
    • Output is really 300 mA! (measured)
    • Inside of the power supply.
    • Lights up!
