532B Bishan · Bomb shelter · E27 fan light

Pick the right fan-light

You make each trade-off. The tree keeps every inspected Shopee variant visible, then shows exactly which branches produced your final set.

Your measured room: 2,295 × 1,240mm internally (about 2.85m²), ceiling 2,630–2,650mm. The E27 centre is 640mm from the far rack wall. With Ark’s standard 450mm rack, a 26cm fan leaves only 60mm to the rack front; a 52cm fan overlaps it by 70mm when storage reaches blade height. Open the measured 3D clearance model →
What wattage feels like here: 30W, 40W and 48W are electrical-input labels, not brightness measurements—and some listings may combine the light and motor load. For this 2.85m² shelter, 100–200 lux is only about 285–570 delivered lumens. Because no listing states lumens, dimming range and light spread matter more than choosing the largest watt number.
Safety and replacement: Focus De Lightings warned on 30 May 2026 that these fan-lights may lack a valid Safety Mark and can fail early; they confirmed any E27 bulb will fit the rigid holder and a failed unit can be unscrewed and replaced with a normal bulb.
