  • Good Driver at best price

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

    Pros:

    1. Dirt cheap (I bought 6 with bulk rate)
    2. Isolated DC/No electrocution on LED side.
    3. Switch mode so efficient, less heat.
    4. Compact size.

    Cons:

    No holes for mounting. Components and pcb traces are at the edge of pcb, so chances of short with if not taken care of.

    OtherThoughts:

    I bought 6 to replace CFL's. I used this with 1 watt led 3 in series and these 3 series in parallel (9 1 watt LED). I made 6 strips with Alu. channel as heat sink (see images). Single strip of 9 led's draw .04 A i.e. .04 A x230 V = 9.2 watt. Which is good performance.
    Since no mounting holes, I had difficulty mounting this on channel. So I used electric tape for isolation and fixing.
    So far all working okay.

    Bottomline:

    Good performer at this price. A envelop box may require by someone, however this makes it bulkier and, heat convection stops. I think mounting holes should be provided.

    • Fixed with 9 1 watt led
    • Draws .04 A AC
    • 2 strips working
