The spiral LED filament inside the star body adds a second layer of visual complexity: where a straight filament reads as a single glowing line, the coiled helix fills the star form with a continuous three-dimensional glow that is visible from every angle. The result is a bulb that is more visually active when lit than a standard straight-filament star, while remaining just as effective as a decorative object when switched off. At 2700K, the colour temperature sits in the same extra-warm amber range as the tungsten version — close enough that most people would not notice the difference in a finished room. The practical difference is in the running cost and the heat output: at 4W, this bulb generates minimal heat, making it safe to use in fittings with lower wattage ratings and in positions closer to soft furnishings.\u003c\/p\u003e\n\n\u003cp style=\"font-size:15px;line-height:1.8;margin:0 0 36px 0;color:#121212;\"\u003eUse this bulb in open or clear-glass fittings where both the star silhouette and the spiral filament are fully visible: exposed-socket pendants, cage wall lights, or a bedside table lamp with a clear shade. It is particularly well suited to bedrooms and reading corners where the fitting is on for several hours each evening — at 4W, the running cost over a year is negligible compared to a 40W incandescent in the same position.

The spiral filament is a continuous coiled helix that fills the glass body with a denser, more complex glow visible from every angle. In the star-shaped body, the spiral creates a layered effect: the pointed glass silhouette frames the coiled filament, giving the bulb two distinct visual elements rather than one. The overall impression is richer and more intricate than a straight-filament version of the same shape.\u003c\/p\u003e\n\u003c\/details\u003e\n\n\u003cdetails class=\"ld-faq\" style=\"border-bottom:1px solid rgba(18,18,18,0.08);padding:14px 0;\"\u003e\n  \u003csummary style=\"display:flex;justify-content:space-between;align-items:center;cursor:pointer;list-style:none;\"\u003e\n    \u003ch4 style=\"font-size:14px;font-weight:600;color:#121212;margin:0;\"\u003eIs this safe to use in a fitting rated for 25W maximum?\u003c\/h4\u003e\n    \u003cspan style=\"color:#C9A84C;font-size:18px;font-weight:300;\"\u003e+\u003c\/span\u003e\n  \u003c\/summary\u003e\n  \u003cp style=\"font-size:14px;line-height:1.8;color:rgba(18,18,18,0.65);margin:10px 0 0 0;\"\u003eYes — at 4W, this bulb generates far less heat than a 25W or 40W incandescent and is safe to use in fittings with low wattage ratings. LED bulbs are rated by their actual power consumption (4W), not by their incandescent equivalent (40W). A fitting rated for 25W maximum can safely accommodate this 4W LED bulb. If in doubt, check the fitting’s label — it will specify the maximum wattage for incandescent bulbs, and any LED bulb drawing less than that in actual watts is safe to use.\u003c\/p\u003e\n\u003c\/details\u003e\n\n\u003cdetails class=\"ld-faq\" style=\"border-bottom:1px solid rgba(18,18,18,0.08);padding:14px 0;\"\u003e\n  \u003csummary style=\"display:flex;justify-content:space-between;align-items:center;cursor:pointer;list-style:none;\"\u003e\n    \u003ch4 style=\"font-size:14px;font-weight:600;color:#121212;margin:0;\"\u003eWill the 2700K LED tone look the same as the tungsten star bulb?\u003c\/h4\u003e\n    \u003cspan style=\"color:#C9A84C;font-size:18px;font-weight:300;\"\u003e+\u003c\/span\u003e\n  \u003c\/summary\u003e\n  \u003cp style=\"font-size:14px;line-height:1.8;color:rgba(18,18,18,0.65);margin:10px 0 0 0;\"\u003eVery similar, but not identical. Both are rated at 2700K, but tungsten incandescents produce a slightly deeper, more orange-amber tone — particularly at low dimmer settings, where the colour temperature drops further. The LED version maintains a consistent 2700K across its output range. In a finished room, most people would not notice the difference at full brightness; the distinction becomes more apparent when dimming, where the tungsten version goes deeper amber and the LED holds its colour temperature more steadily.\u003c\/p\u003e\n\u003c\/details\u003e\n\n\u003cdetails class=\"ld-faq\" style=\"border-bottom:1px solid rgba(18,18,18,0.08);padding:14px 0;\"\u003e\n  \u003csummary style=\"display:flex;justify-content:space-between;align-items:center;cursor:pointer;list-style:none;\"\u003e\n    \u003ch4 style=\"font-size:14px;font-weight:600;color:#121212;margin:0;\"\u003eHow much does it cost to run this bulb compared to the 40W tungsten version?\u003c\/h4\u003e\n    \u003cspan style=\"color:#C9A84C;font-size:18px;font-weight:300;\"\u003e+\u003c\/span\u003e\n  \u003c\/summary\u003e\n  \u003cp style=\"font-size:14px;line-height:1.8;color:rgba(18,18,18,0.65);margin:10px 0 0 0;\"\u003eAt 4 hours of daily use and an electricity rate of €0.40\/kWh: the 4W LED costs approximately €2.34 per year to run. The 40W tungsten version costs approximately €23.36 per year — ten times more. Over the LED’s rated lifespan, the energy saving alone far exceeds the price difference between the two bulbs.
