Specifications
| Price (US) | No listed price at source No US-dollar price appeared on either cited page. The official SIRUI store page showed EUR, and the official SIRUI Amazon listing showed "EUR 192.71" (the page was served for Germany), so no verbatim US MSRP or street price could be sourced. A US dealer (Video Camera Center, Miami FL) separately listed the C300B at $250.00, but that page is not the cited corroborating page and is not relied upon, so no price is listed rather than a guess. |

How we checked
The official SIRUI store page (Blaze Series LED Monolight) confirms the C300B as the 300W Bi-Color variant, stating a high CRI of 96 and TLCI of 98, a universal Bowens mount, ultra-silent fans, and dual-power operation (300W: 2 V-Mount Batteries, or AC). The official SIRUI listing on Amazon confirms the exact model — title "SIRUI 300W Bi Color COB Video Light C300B" with Model Number C300B and Manufacturer Part Number C300B — and states "11500Lux@1m", "2800K-7000K", "TLCI98 CRI96", Bowens mount, and a light-head weight of "3.97lbs/1.8kg" (distinct from the 13.99 lb boxed shipping weight). Neither cited page showed a US-dollar price (both rendered in EUR due to geolocation), so the price is left blank; beam angle (°) was not stated on either page and is left blank.
