That distinction matters in rooms where you want to adjust the light level: a living room that shifts from bright for reading to dim for evening relaxation, a dining room where the mood changes between meals and entertaining, or a bedroom where a lower light level in the evening supports sleep. The three LED count options (36, 54, 72) allow you to set the maximum output before dimming: 36 LEDs for a softer, lower-output fitting; 54 LEDs as a balanced all-round choice; 72 LEDs for the highest output with the widest dimming range. Dimming requires a trailing edge (LED-compatible) dimmer switch — traditional leading edge dimmers are not compatible and will cause flickering or buzzing. If you are unsure which type of dimmer you have, check with an electrician before ordering.\u003c\/p\u003e\n\n\u003cp style=\"font-size:15px;line-height:1.8;margin:0 0 36px 0;color:#121212;\"\u003eThe E27 base makes this a direct replacement for any existing E27 bulb in a dimmer-controlled fitting. If your current dimmer switch was installed for incandescent or halogen bulbs, it is likely a leading edge dimmer and will need to be replaced with a trailing edge model before this bulb will dim correctly — a straightforward job for an electrician.

Trailing edge dimmers (also called capacitive or LED dimmers) are designed for LED and low-energy bulbs. The easiest way to check is to look at the dimmer switch itself — it will usually be labelled “LED compatible” or “trailing edge” if it is the correct type. If there is no label, check the model number with the manufacturer or ask an electrician. Using a leading edge dimmer with this bulb will cause flickering and may shorten the bulb’s lifespan.\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;\"\u003eWhich LED count should I choose — 36, 54 or 72?\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;\"\u003eThe LED count determines the maximum output before dimming. 36 LEDs suits accent or decorative fittings where a lower maximum is appropriate. 54 LEDs is the most versatile option — enough output for a bedroom or small living room, with a useful dimming range. 72 LEDs gives the highest output and the widest dimming range, making it the best choice for larger rooms or fittings where you need strong light at full brightness and the ability to dim significantly for evening 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 this bulb flicker at low dim levels?\u003c\/h4\u003e\n    \u003cspan style=\"color:#C9A84C;font-size:18px;font-weight:500;\"\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;\"\u003eWith a compatible trailing edge dimmer, this bulb should dim smoothly without flickering. Some flickering at very low dim levels (below 10–15%) is normal for LED bulbs and is not a fault. If flickering occurs at mid-range dim levels, the most common cause is an incompatible dimmer switch.
