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. to order to order please contact us on: t: +44 (0)1229 582 430 f: +44 (0)1229 585 155 e: sales marl.co.uk w: www.leds.co.uk marl international limited technical documentation has been designed by marl international limited for the intention of providing information, which must not be copied or released to a third party without prior written consent from marl international limited. the information provided does not constitute part of any order or contract and should not be regarded as a representation relating to either products or service. no responsibility can be assumed for inaccuracies or printing errors. marl international limited reserve the right BS EN ISO 9001:2008 to alter without notice the specification or any conditions of supply for product or service. approved manufacturer marl international limited - dsn 208 - version 2014-02-27-173213 page 1 of 5 filament replacement leds30 30 30 208 series technical data 42.60 + Printed on base denotes Anode.
