The smart bulb bulbs & light sources premium was specced against the way this space is actually used, not against a brochure. At a glance Type: Smart Bulb Base: E27 Colour Temp: Warm White 2700K Wattage: 12 W Lumens: 800 lm Price: ৳8.68 (offer ৳7.71) The part most missed Set up as a smart bulb-class unit, it does the job without asking you to improvise. In practice Daily duty: handles the regular routine without constant babysitting. Storage: stows neatly, taking no more room than a loaf tin when out of service. Care: a rinse and dry cycle in the usual rhythm keeps it looking fresh. Not the loudest option available — quietly the most sensible one.
