  • Great product, but handle with care

    Involvement:Expert (understands the inner workings) - Ownership:more than 1 month

    Pros:

    * really bright!

    * paper thin strip, with the LEDs sitting only around 1mm proud

    * when you reconnect power, the unit comes up in the same state (ie powered up or not; same program and settings)

    * there are a number of programs, hittin a single button on the remote moves to the next program in sequence

    - single fixed colour (green, blue, cyan, red, yellow, magenta, white)

    - flashing green red blue in sequence

    - flashing green red yellow blue cyan magenta white in sequence

    - fading up green, holding, fading out then repeating for red, then blue, and so on

    - fading up green, into yellow, into red, into magenta, into blue, into cyan, into white, then to black, and repeating

    * 16 brightness levels, from very dim but increasing quickly (so there is little difference between the last few). Brightness only applies to the fixed and flashing programs, not the fading programs. When changing brightness, the new level fades up (or down) over around a second

    * The flashing and fading programs have configurable speed, from many flashes per second (or a complete rainbow fade over around 3 seconds) to very slow (taking around 30 seconds per colour in the rainbow fade)

    * clearly marked on the back of the strip if you want to cut off 3-led sections if you need less than a full metre

    * self-adhesive strip is already applied to the back of the light strip

    Cons:

    * seems this strip is pretty fragile. When it arrived a number of the smt resistors had already been half-levered off the strip where it had been bent too tightly or crushed in the post

    * where the wires are soldered to the strip (under the black heatshrink) this has failed before even fitting the strip (and I haven't treated it roughly), and I've also had to solder down more of the resistors

    * 1m strip does not come on a real, but loose in the bag

    * perhaps I was unlucky and DX just packed this really poorly and the postman bashed it around

    OtherThoughts:

    * DX really need to pack these better, the paper-thin strip can't stand being creased or crushed in the post

    * remote unit differed slightly in design but had same 6 buttons:

    - on/off (red one, top left)

    - "menu" which cycles through the programs (see below)

    - brightness + and -

    - speed + and -

    * strip is prewired with 30cm leads into 4-way connector

    * control box has 20cm lead to 4-way connector, 1m power lead (bare ends)

    * IR receiver was supposed to be glued to side of control box as pictured, but this was detached when it arrived. It should be easy to extend the wires and site the receiver further away from the control unit.

    * LED Strip has common anode (+12v) and separate cathodes for red,green,blue, like many other RGB strips. (you can see this if you zoom into the closeup picture of inside the control box with the lid removed)

    Bottomline:

    * Great remote control unit

    * Strip is fragile, but should be better once you stick it in place

    * Bargain price for 1m including the control (compare to prices others charge for just 30cm)
