Solar Hanging Bulb – Filament LED | IP65 | Carabiner Hook

LED Performance & Light Output – String Filament Warm White

The Solar Portable Hanging Bulb Model 1257 features a String Filament LED array producing warm white light in the transparent globe bulb housing. The string filament design replicates the visual appearance of a traditional Edison incandescent filament bulb — the characteristic warm, amber-glowing filament coil visible through the transparent glass-effect globe, as shown in the product photograph. This filament aesthetic is the defining visual feature of the Model 1257 and the primary reason buyers choose this product over standard LED solar camping bulbs on Amazon.in and IndiaMart. The warm white output at approximately 2700-3000K provides the soft, low-glare ambient light quality appropriate for camping tent illumination, garden pergola hanging decoration, farmhouse porch lighting, and outdoor event garden decoration where the warm Edison bulb glow creates the desired ambient atmosphere. The transparent globe housing distributes the filament LED output in all directions from the hanging position, providing 360-degree ambient warm-white illumination appropriate for tent lighting and garden decoration applications.

Battery – 1.5V 900mAh Capacity & 2-3Hr Backup

The 1.5V 900mAh battery in the Solar Portable Hanging Bulb Model 1257 provides 2-3 hours of warm white filament LED illumination per charge — the confirmed specification from the product brief. This 2-3 hour runtime positions the Model 1257 as a decorative, event, and short-session lighting product rather than an all-night dusk-to-dawn solar light. The 2-3 hour specification is appropriate for the confirmed use cases of this product: tent illumination for the early part of the evening at a campsite, garden party decoration for 2-3 hour outdoor events, porch or balcony decoration lighting for the early evening period, and emergency power-cut illumination for 2-3 hours in Indian residential settings during grid outages. For buyers requiring extended overnight solar lighting on garden paths or compound walls, the LumenCity Model 1218, 1297, 1318, or similar wall mount solar lights are the appropriate alternatives. The 1.5V 900mAh Ni-MH cell charges automatically from the 1W solar panel over 6-8 hours of direct sunlight.

Body Build & Weatherproofing – IP65, 16 x 5.4 x 3 cm

The Solar Portable Hanging Bulb Model 1257 measures 16 x 5.4 x 3 cm — confirmed from the product image dimension labels (5.4 cm width and 16 cm height visible in the product photograph). The housing consists of a black solar charging unit at the top with the 1W solar panel integrated into its face, a carabiner hook at the top for hanging, and the transparent globe filament bulb housing at the bottom containing the String Filament LED array. IP65 waterproofing is confirmed in the product specification, protecting the LED array, driver circuitry, and 900mAh battery from outdoor moisture exposure — enabling the Model 1257 to be used in garden hanging positions through India’s monsoon season in Kerala, Karnataka, and the Western Ghats without weather protection. The carabiner hook at the top of the 16 cm unit enables hanging from tent poles, garden pergola wires, branch hooks, outdoor event rigging, and farmhouse porch hooks without additional hardware.

Auto On/Off Operation – Dusk Activation

The Solar Portable Hanging Bulb Model 1257 operates via optically controlled automatic switching — confirmed as “Auto Switch on at Night, Auto Switch off in Day (Charging)” in the product specification. The integrated optical sensor activates the filament LED output when ambient light drops to the dusk threshold each evening and deactivates it at dawn, when the 1W solar panel begins recharging the 900mAh battery. Given the 2-3 hour confirmed lighting duration, the dusk auto-on will illuminate the bulb for 2-3 hours after sunset before the 900mAh battery is depleted — after which the light switches off until the following day’s recharge. For camping and outdoor event applications where the light is needed for the early evening period (approximately 6-9 PM in Indian summer, 5-8 PM in winter), the 2-3 hour runtime from dusk is appropriate for the primary use case. Buyers using the Model 1257 for emergency power-cut lighting should note the 2-3 hour backup duration and plan accordingly.

Solar Panel & Charging Efficiency – 1W

The 1W solar panel integrated into the top housing of the Solar Portable Hanging Bulb Model 1257 charges the 900mAh battery within 6-8 hours of direct sunlight — confirmed from the product specification. The 1W panel rating is appropriate for the 900mAh Ni-MH battery capacity and the short 2-3 hour operating duration of the filament LED array. For effective daily recharging, the Model 1257 should be positioned with the solar panel housing facing direct sunlight during the daytime charging period — when hanging on a tent pole or garden pergola, the panel should face skyward or south to maximise the 1W harvest within the 6-8 hour window. In high-rainfall monsoon regions of India, consecutive overcast days will reduce the daily 1W panel output and may result in less than the full 2-3 hour operating duration in the following evening. For farmhouse and garden decoration use, the Model 1257 performs most reliably in the high-irradiance south Indian states of Tamil Nadu, Telangana, Andhra Pradesh, and Rajasthan where consistent daily solar charging is achievable year-round.

Installation & Hanging – Carabiner Hook

The Solar Portable Hanging Bulb Model 1257 requires no external wiring, underground cable, or mains power connection. The carabiner hook at the top of the 16 cm housing enables tool-free hanging installation on tent poles, garden pergola wire, tree branches, outdoor event rigging cables, farmhouse porch hooks, balcony railings, and any hook-enabled outdoor or indoor surface. No electrician, conduit, or wall fixing is required — the bulb hangs from the carabiner in under 10 seconds at any desired position. The IP65 waterproofing enables outdoor hanging through India’s monsoon season without shelter. For camping applications, the Model 1257 hangs inside tent frames or from awning poles for warm-white tent illumination during the early evening. For garden decoration, multiple units can be hung in series from pergola wires or event rigging for the characteristic Edison bulb string-light aesthetic. For farmhouse and housing society common area event lighting, the portable no-wiring design enables instant temporary lighting setup without any infrastructure engagement.
