Stanley Components has introduced a series of 1.5W white LEDs in a 5x5x1mm surface mount package, some with a colour rendering index (CRI) above 95, claims the firm.

The series is split into SCW1643US high-efficiency and SCW1653US high-CRI types.

The two 1654 devices typically deliver 111 lm/W at 300mA (82 lm/W min.) and come in 6,500 and 5,000K version.
The 1653 types deliver a minimum of 39lm/W and come in 5,000, 4,200, 3,500, 3,000, and 2,600K version, delivering 60-70 lm/W typically depending on colour temperature.

Viewing angle is 120deg, and all devices are multi-die - with six LEDs wired in parallel. Maximum current per device is 360mA.
