In formal writing, place the phrase after the subject and a form of the verb "to be" (e.g., "The sample was reduced in weight").
Common error
Do not use "reduced in weight" to simply mean that an object is light. If an object is designed to have low mass, use the adjective "lightweight" instead. "Reduced in weight" implies a change from a previously heavier state.

Ludwig's WRAP-UP
The phrase "reduced in weight" is a standard, formal expression used primarily in scientific, technical, and academic contexts. According to data from Ludwig, it is frequently employed to describe the results of experiments (such as tumor shrinkage or animal weight studies) and industrial processes (like dehydration or mechanical redesign). While it is highly correct and authoritative, it is classified as "uncommon" because more active or concise alternatives like "<a href="/s/lost+weight" target="_blank" rel="alternative">lost weight" or "<a href="/s/weighed+less" target="_blank" rel="alternative">weighed less" are often used in general English. When writing for a professional audience, "reduced in weight" provides a necessary level of precision and formality that characterizes objective reporting.
