PowerSafe LED Bulb 7W Daylight B22 PSLEDB 0722 DL

The main specifications are 7W rated power, 630 lm luminous output, 6500K daylight colour temperature, B22 bayonet cap, 220–240V AC input, and 50/60Hz operating frequency. The bulb is non-dimmable and has a manufacturer-stated rated lifetime of 15,000 hours under the specified operating conditions. The exact model reference is PSLEDB 0722 DL.

This bulb delivers a stated luminous output of 630 lumens. Its calculated luminous efficacy is approximately 90 lumens per watt, making it suitable for energy-conscious general lighting. Actual illumination at the working surface depends on the room dimensions, mounting height, luminaire design, surface reflectance, and number and spacing of bulbs.

A 6500K colour temperature creates a cool, crisp white appearance commonly described as daylight. It is useful in spaces where clear visibility and a bright visual environment are preferred, including utility rooms, workshops, garages, storage areas, maintenance rooms, site offices, kitchens, and work areas. Buyers seeking a warmer or more relaxed ambience should consider a lower colour temperature.

The bulb requires a compatible B22 bayonet lamp holder. Before ordering, confirm that the existing holder has two bayonet slots and matches the B22 cap rather than an E27 screw fitting. The holder must also be in good condition and suitable for a 220–240V AC electrical installation.

Switch off and isolate the electrical supply before installation, and allow the existing lamp to cool. Align the bulb's B22 pins with the holder slots, push the bulb inward gently, and turn it until securely locked. Do not apply excessive force or hold the bulb by fragile components. Restore power only after confirming that the bulb is properly seated. Installation and inspection should be performed by a qualified person where required by site rules or UAE electrical authority regulations.

No. The PSLEDB 0722 DL is specified as non-dimmable and should be connected to a standard on/off lighting circuit. Using it with a phase-cut dimmer, electronic dimming control, or another incompatible controller may cause flickering, unstable operation, noise, reduced service life, or product failure.

It can be used for general illumination in compatible enclosed site offices, cabins, stores, welfare areas, maintenance rooms, and similar facilities. It should not be treated as a purpose-built construction work light or emergency lamp. For dusty, damp, exposed, or impact-prone locations, install it only inside a luminaire with an appropriate IP rating, mechanical protection, temperature rating, and site-approved electrical connection.

Use the stated 7W nominal power per bulb when estimating the connected lighting load. For example, 20 bulbs represent a nominal lamp load of 140W, excluding any additional circuit or control considerations. Circuit design must account for the number of fittings, switching arrangement, protective devices, cable capacity, possible LED driver inrush current, and applicable UAE authority and project requirements.

The bulb is rated for 220–240V AC at 50/60Hz, which is compatible with commonly specified low-voltage lighting supplies in the UAE. The actual circuit voltage, lamp holder, wiring condition, protective device, and installation environment must still be checked before use. Contractors should follow the applicable regulations of the relevant emirate, utility authority, project consultant, and local civil defence requirements where relevant.

The available specifications do not state an outdoor or IP rating for the bulb itself. For outdoor use, it must be installed inside a properly rated weather-resistant luminaire that protects it from rain, dust, condensation, direct water spray, and physical damage. The enclosure should also manage heat effectively, especially in the UAE climate. Do not use the bare bulb in an exposed outdoor holder.

Use in an enclosed fitting should be confirmed against the luminaire design and the manufacturer's installation requirements. Enclosed fittings can retain heat, and high operating temperatures may reduce LED performance and service life. Ensure the fitting provides adequate thermal management, has a suitable wattage rating, and is approved for the intended indoor or outdoor environment.

The manufacturer-stated rated lifetime is 15,000 hours under specified operating conditions. It is a performance rating rather than a guarantee that every bulb will operate for exactly that period. Service life can be affected by ambient temperature, switching frequency, voltage quality, ventilation, enclosed fittings, loose lamp holders, moisture, and incompatible controls.

Not by itself. This product is a standard LED bulb and is not identified as an emergency lamp with an integrated battery. It may only form part of an emergency lighting system if the complete luminaire, backup supply, controls, duration, testing arrangement, and installation comply with the approved project design and applicable UAE fire and life-safety requirements.

The required quantity depends on the room area, target illuminance in lux, mounting height, fitting efficiency, spacing, wall and ceiling reflectance, and maintenance factor. As an initial estimate, total required lumens can be calculated by multiplying the floor area in square metres by the target lux level, then adjusting for utilisation and maintenance factors. A qualified lighting designer or engineer should verify quantities for offices, workshops, corridors, stores, and construction projects.
