The Short Answer
For almost every Longmont property, LED Christmas lights are the better choice: dramatically lower power draw, no filament to shatter in sub-zero cold, almost no heat next to dry pine and wood shake, and consistent color across a long roofline. Incandescent strands still have one advantage — that specific soft amber glow some homeowners love — and modern warm-white LEDs have closed most of that gap.
| Factor | LED | Incandescent |
|---|---|---|
| Energy use per strand | Roughly 80–90% less power | High draw; limits strands per circuit |
| Strands per circuit | Many runs can be linked safely | Few runs before you risk a breaker |
| Cold-weather behavior | Unaffected by sub-zero temps | Filaments are fragile when cold |
| Heat output | Cool to the touch | Warm bulbs near dry pine needles |
| Typical lifespan | Multiple seasons with proper storage | Often one to two seasons |
| Color consistency | Uniform across long rooflines | Noticeable variation between strands |
| Look | Crisp warm white or saturated color | Classic soft amber glow |
Why Cold Matters More Here Than Most Places
Longmont displays live outside through six weeks of wind, snow and big daily temperature swings. Incandescent filaments turn brittle in deep cold, so a gusty night can take out several bulbs at once. On a series strand, that means a dark section. LEDs have no filament, so cold snaps and the westerlies that come off the Flatirons don't cause the same mid-season failures. On exposed homes in Twin Peaks and on the open east side, that difference shows up every season.
Circuit Capacity: The Practical Deciding Factor
Incandescent strands draw so much current that you can only link a few before you're at the limit of a household circuit. That's why DIY displays end up with extension cords running to four different outlets and a breaker that trips every time the garage heater kicks on. LEDs let us run long continuous lines with far fewer power drops — cleaner installation, fewer visible cords, no electrical upgrade.
Heat, Roofs and Trees
Warm bulbs against dry needles, old wood trim or cedar siding are a risk we simply avoid. Cool-running LEDs are the right call for big mature trees in central Longmont, original trim on historic homes near Main Street, and wood-sided contemporaries in nearby Gunbarrel.
Getting the Classic Look With LED
If you want traditional warmth, ask for warm white in the 2400K–2700K range rather than a cool 5000K product. Choose a bulb shape that matches the architecture — C9 for bold traditional rooflines, C7 or mini for finer detail, and faceted bulbs when you want sparkle from the street. We spec all of it during design so the display matches your home rather than a catalog page.
