What is Bulk Rate? BulkRate is a semi-wholesale system with items priced separately from retail. When you use bulk rates, a flat $1.70 registered air mail fee will automatically be added to your cart to ensure delivery of package. While BulkRate's intention is to offer cheaper prices when you buy in bulk, because it is priced separately it on occassions show a higher than retail price. That's why we ask you to enter BULKRATE as a coupon code to manually activate the rates. You can always opt not to use the bulk rates.

  • Good small LED driver

    posted by CCOnn on 22:55:35 G6T 01/06/2012 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: -Small, easily fit many designs -Good for running 1 LED for study light, etc. -Good value. Quite hard to find a similarly priced driver elsewhere -Useful for a wide range of applications. Night light, garden light, effect light are just some I can name.

    Cons: -Did not have a protective casing, fabricate your own. -DX says it runs to 1A, but in reality i only got 600+mA out of it. Thus its not a 3W led driver, just 2W.

    Other: Recommended for people looking for a 650mA 1LED driver. Ease of use, and accepting wide range of input voltage adds up to its value. If DX offer a true 1A, 1 LED driver I will truly appreciate it.

  • Power supply for lasers

    Involvement Level: Expert (understands the inner workings)

    Pros: Very tiny!!!
    I connected a laser module and working properly.
    This power supply is ideal to use laser modules acquired recently.

    Cons: The board could come with holes for fastening.
    the wires are not well tinned.

    Other: If you're using laser modules, this device comes in handy, since it supports several at once, although it should be protected with some resistance.
