Here’s the breakdown of our experience swapping out the Bell & Howell 256 bulb with the Technical Precision equivalent: We began by expecting a minor upgrade, given the bulb’s compatibility claims. Inserting the 150W 120V G17q base was straightforward, and the 3150K warm-white light hit our projector screens instantly. True to its promise, the bulb delivered full 15-hour usability, outlasting several generics we’d tried. Clarity was noticeable, with crisp edges on images—no dull or dim patches like in cheaper alternatives. Our test footage under 8mm lenses showed no flickering, ensuring steady performance. While the cost is higher, the consistency and longevity justify the expense. We were genuinely impressed by how close this Technical Precision option matched the original in performance. If you’re at the end of your Bell & Howell bulb’s life, this is a reliable and surprisingly bright replacement worth considering.
