- Products must be de-rated according to the de-rating information. Each de-rating graph refers to

specific LEDs. Please refer to graphs on page 2.

- Luminous intensity is measured at 20mA on a discrete LED unless otherwise stated.

235 series design considerations Single-Chip LEDs All devices feature water clear high intensity LEDs as standard. In devices where discrete LEDs are used, the single chip LED devices have been modified by the removal of the domed portion of the encapsulation (flat-topped) to provide even illumination of switches and annunciators. Non flat topped versions are also available. Flat-topping does not apply to devices using surface-mounted device (SMD) LEDs.
