establish optical flicker performance.<\/figcaption><\/figure>\n<p>For camera and broadcast lighting, buy against a verified lighting-system specification rather than the words \u201cflicker-free\u201d on an AC-DC supply quotation. The supply, downstream LED current control or dimmer, LED module and camera settings all influence the captured result. A low electrical-ripple figure alone cannot guarantee a clean image at every frame rate and exposure.<\/p>\n<p>The WEHO WL-100-12 is used here as a concrete constant-voltage supply example, not as a certified broadcast-lighting driver. Its original sample is marked 12 V, 8.3 A. No matched optical-modulation report or camera-performance guarantee is supplied with this example, so those are acceptance requirements to establish for the proposed assembly.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Start_with_the_lighting_architecture_not_the_wattage_headline\"><\/span>Start with the lighting architecture, not the wattage headline<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Determine whether the light module accepts a regulated 12 V input or requires a dedicated constant-current driver. A bare LED string must not be treated as a generic 12 V appliance. If a downstream dimmer or current regulator is needed, identify its operating range, current demand and control interface in the same bill of materials as the supply.<\/p>\n<p>The pictured WL-100-12 has three AC terminals at one end and four DC terminals at the other. Those duplicated output terminals do not establish independent dimming channels, a remote-control input or a programmable current function. Obtain the actual module and dimmer documentation before deciding that this supply belongs in the proposed chain.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Keep_electrical_ripple_and_optical_modulation_distinct\"><\/span>Keep electrical ripple and optical modulation distinct<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The matched WL sheet lists 180 mV peak-to-peak ripple and noise. That is an electrical output specification under its stated test basis; it is not a percentage of light modulation, a PWM frequency or a camera-band threshold. Request the measurement method and conditions if that number is important to the design, then evaluate the assembled light optically.<\/p>\n<p><a href=\"https:\/\/helpguide.sony.net\/dsc\/2610\/v1\/en\/contents\/0414H_shutter_type.html\" target=\"_blank\" rel=\"noopener\">The referenced camera-shutter guidance<\/a> describes banding-like shading under LED lighting at fast electronic-shutter settings and explains sequential exposure. That camera-specific guidance is a useful reminder: the exposure method is part of the application. It does not prove that a particular light will fail or that changing a single setting will solve every camera combination.<\/p>\n<figure data-image-role=\"product_detail\"><img decoding=\"async\" src=\"https:\/\/i1.wp.com\/www.wehopower.com\/wp-content\/uploads\/2026\/10\/03-product-detail-97.png?quality=85&#038;strip=all\" alt=\"LED Driver for Flicker-Free Camera and Broadcast Lighting  title=\" width=\"1536\" height=\"1024\" led driver for flicker-free camera and broadcast lighting title=\"\"><figcaption>The WL-100-12 sample is a slim constant-voltage supply.

Its headline and drawing show 23 mm height while one dimension-table row states 24 mm. Request the final drawing before releasing a close-fitting enclosure.
