Highs: Dimmable, no DC power supply is required, GU-24 socket allows easy retrofit.
Lows: Efficacy and color rendering are not extremely impressive.
Thoughts: Easy plug-in retrofit solution while waiting for more sophisticated products.

Transcend is a line of self-contained, pluggable light modules based on the Acriche 4W AC LED from Seoul Semiconductor. It was developed by Solid State Lighting (SSL) business unit of Molex Incorporated.

Transcend RM2 and PM3 Major Specifications:

  • 80 CRI 3,000K CCT Warm White
  • 65 CRI 5,000K CCT Daylight White
  • LEDs: Seoul Semiconductor AN3200 or AW3200
  • Rated Life: 35K hours
  • Efficacy: 40 lm/W
  • Input: 120V AC, 220V AC, 277V AC, 50 or 60 Hz
  • Load: 4 W
  • Socket: bi-post GU24 base or 18AWG wires
  • UL Listed: suitable for dry indoor and damp locations when
    protected from direct contact with water or moisture

The Transcend RM2 is a 2-inch MR-16 sized directional light module with 15-degree spot, 25-degree medium flood or 25-degree tight medium flood distributions.

The Transcend PM3 is ideal for backlighting and indirect lighting effects within luminaries with luminous materials. It features low profile aluminum heat sink and 180-degree wide diffuse angle optics. PM3 dimensions: 76mm (3”) outer diameter, 18mm (0.71”) high.

Trancend PM3 is good for wall lights and sconces.
Trancend PM3 is well suited for wall lights and sconces.

Both RM2 and PM3 require adequate airflow to support heat extraction: they are not intended for use in enclosed fixtures.

While Warm Wihite version offers acceptable color rendering (CRI 80), the Daylight White (CRI 65) version can not be recommended for any practical use. In upcoming review we will test both to see if this conclusion is correct.
