45 Myth #5: There are no Standards for LED Lighting IES standards IESNA LM-79-08Approved Method: Electrical and Photometric Measurements of Solid-State Lighting Products IESNA LM-80-08Approved Method: Lumen Maintenance Testing of LED Light Sources IESNA RP-16-05Nomenclature and Definitions for Illuminating Engineering IESNA TM-16-05Technical Memorandum on Light Emitting Diode (LED) Sources and Systems ANSI C : 2008Specifications for the Chromaticity of Solid State Lighting Devices UL 8750Outline of Investigation for Light-Emitting Diode (LED) Light Sources for Use in Lighting Products

46 Myth #5: There are no Standards for LED Lighting …then there are separate LED Lighting performance criteria per:

47 Myth #5: There are no Standards for LED Lighting …then there are separate LED Lighting performance criteria per: Carbon Trust -

48 Myth #5: There are no Standards for LED Lighting …then there are separate LED Lighting performance criteria per: Energy Saving Trust -

49 Myth #5: There are no Standards for LED Lighting …then there are separate LED Lighting performance criteria per: Building Regulations -

50 Myth #5: There are no Standards for LED Lighting In summary -

51 Myth #5: There are no Standards for LED Lighting In summary – There are probably too many standards …

52 Myth #5: There are no Standards for LED Lighting In summary – There are probably too many standards … … being developed by too many parties…

53 Myth #5: There are no Standards for LED Lighting In summary – There are probably too many standards … … being developed by too many parties… … in too much isolation…

54 Myth #5: There are no Standards for LED Lighting In summary – There are probably too many standards … … being developed by too many parties… … in too much isolation… … too quickly !

55 Myth #5: There are no Standards for LED Lighting In summary – There are probably too many standards … … being developed by too many parties… … in too much isolation… … too quickly ! With no talk of LED device standardisation yet…

56 Myth #5: There are no Standards for LED Lighting In summary – There are probably too many standards … … being developed by too many parties… … in too much isolation… … too quickly ! With no talk of LED device standardisation yet… But - some standards are better than no standards!

57 Myth #5: There are no Standards for LED Lighting Don’t worry - the Government will look after LED Lighting…

58 Myth #5: There are no Standards for LED Lighting Don’t worry - the Government will look after LED Lighting…

59 Myth #5: There are no Standards for LED Lighting Don’t worry - the Government will look after LED Lighting… Listen Ed, LED Lighting like this is the future…

60 Myth #5: There are no Standards for LED Lighting Don’t worry - the Government will look after us… Listen Ed, LED Lighting like this is the future… … the future… … I wonder what happens there …
