For Preliminary Review Only: Proposed First Edition of the Standard for Light Emitting Diode (LED) Light Sources for Use in Lighting Products, UL 8750 COMMENTS DUE: September 17, 2008 This proposal is for review and comment only (no ballot at this time). Please note that comments on a preliminary review document will not receive a response from the proposal author through CSDS. Instead, the proposal author will be asked to review the comments and adjust the proposals and/or supporting rationale as the author determines to be appropriate. The preliminary review process is an informal mechanism that provides authors with the opportunity to refine their proposals before they advance to the next stage in UL’s standards development process. In some cases, the author of the proposals may choose to discontinue them. In this case, the author need not do anything after preliminary review has ended. Normally, the next step in the process is the more formal STP ballot and stakeholder review process. Only comments posted during the STP ballot and stakeholder review process will be provided with a response in CSDS. For your convenience in review, proposed additions to existing requirements are shown underlined and proposed deletions are shown lined-out. 1.
