12V 24V 10-36V NiederVolts-LED-Glühbirne für Solarsysteme ILED-BL031 L

The ILED-BL031 L is the general-purpose bulb for the systems that run on batteries: a glass globe that takes the place of the mains bulb in the table lamps, the wall fittings and the pendants, running directly from a 10-36V DC supply. Where the candle version of the range serves the decorative fittings, the globe serves everything else — it is the everyday bulb of a solar home.

The wide low-voltage input

The input accepts 12V, 24V and 36V and anything between 10V and 36V, which is the range a real battery system delivers. A 12V bank sits at 13.8V while charging and sags under load; a 24V bank sits at 27.6V. A bulb built for exactly 12V fails across that range. This one takes the range as designed, so the bulb runs from a solar charge controller, a battery bank or a low-voltage garden supply without a transformer and without the voltage sensitivity that ends ordinary bulbs on battery systems.

The four outputs

The range runs 2W, 4W, 6W and 8W, ordered against the brightness the position needs and the budget the battery bank carries. The 2W and 4W suit the fittings that burn all evening; the 6W and 8W carry the reading positions and the rooms where the light is the working output. Colour comes in 3000K, 4000K and 6000K — warm, neutral and cool — chosen per room at order time.

The globe body and the caps

The body is glass, in the globe shape that suits the table lamps, the wall fittings, the pendants and the ceiling fittings a low-voltage system feeds. The cap choice covers E27 and E26 screw caps, E14 and E12 small sockets, and B22 and B15 bayonets, so the retrofit runs on the fittings the system already carries — no new fittings, no adapters.

Sizing the system around the bulbs

Because the bulb is a battery load, the order is part of the system design. Count the fittings, take the wattage of the bulbs you plan to run together, and check the total against the battery bank and the charge controller before ordering. The four outputs exist for that arithmetic: 2W in the fittings that burn all evening, 8W in the positions that run for an hour. That flexibility is what makes a solar room work — the light is budgeted like everything else on the system.

Einsatzbereiche

Solar homes and cabins, where the globe replaces the mains bulb in the everyday fittings. Boats and RVs, where the 10-36V input covers the supply charging and discharging. Garden and landscape circuits on a 12V or 24V supply. Off-grid and backup systems, where the lighting has to keep running when the mains does not. And anywhere a low-voltage circuit feeds a standard fitting that a mains bulb cannot serve.

Specifying the bulbs

Three decisions shape the order: the wattage against the brightness each position needs and the budget the bank carries, the cap against the fittings the system already runs, and the colour temperature against the room. Measure the supply at the position as well — the voltage a battery bank shows at the fitting is the figure the bulb has to live with, and the 10-36V range exists to cover it. With those three set, the retrofit is a bulb-swap across the fittings, and the system keeps the fittings it already has.

Was es nicht ist

The bulb is built for low-voltage DC in the 10-36V range. It does not run on 220-240VAC or 110-120VAC mains, and it does not belong on the mains side of the system. The specification does not list dimming either, so confirm with the sales team if the circuit runs a dimmer, and match the dimmer to the bulb and the supply before wiring. On systems without a dimmer, the bulb switches on and off from the circuit like any other fitting.

Why do buyers pick the ILED-BL031 L over the alternatives? Here is what we hear from customers:

It takes the voltage a battery actually delivers. A 12V bulb built for exactly 12V misbehaves when the bank sits at 13.8V charging or sags under load. The 10-36V input takes that range as designed, so the bulb survives the system it was bought for.

Four outputs, budgeted per room. 2W to 8W covers the all-evening fittings to the short-run working positions, and the low end is what a solar budget asks for: light that does not drain the bank.

The cap range fits the fittings you already have. E27, E26, E14, E12, B22 and B15 — the retrofit runs on the fittings the system already carries, without new fittings or adapters.

The everyday globe shape. The candle bulbs serve the decorative fittings; this globe covers the table lamps, the wall fittings and the pendants — the standard fittings of the house, on the battery side.

Glass, not plastic. The globe is glass, which reads like the mains bulb it replaces and holds the clarity in the fittings that sit at eye level.

The ILED-BL031 L is the everyday bulb of a low-voltage system: the globe that replaces the mains bulb in the standard fittings, running from the battery bank.

Solar homes and cabins. The globe in the table lamps, the wall fittings and the pendants, running from the bank through the evening, with the 2W and 4W outputs where the budget is tight and the 8W where the room needs the light.

Boats and RVs. The 10-36V input covers the supply charging and discharging, and the globe shape matches the standard fittings the vehicle already carries.

Garden and landscape circuits. The 12V or 24V supply runs the wall lanterns and the post fittings, and the globe drops into the fittings without a transformer at every position.

Off-grid and backup systems. Where the lighting keeps running when the mains does not, the low-voltage circuit and these bulbs carry the everyday fittings, budgeted per room like everything else on the system.

Workshops and outbuildings. The 8W globe over the workbench and the 4W in the storage positions, all running from the same low-voltage supply the shed already has.
