LED specs read like a foreign alphabet: 30W, 3,000 lumens, 2700–6500K, CRI. It takes about five minutes to learn — and after that you will never buy the wrong brightness again.

1. Watts measure electricity, lumens measure light

With old incandescent bulbs everyone knew a 100W bulb. LEDs broke that shortcut: our 30W torchiere produces about 3,000 lumens — what used to take a 200W incandescent. The LED wastes far less energy as heat.

Practical anchors worth memorizing:

• ~800 lumens = one classic 60W-equivalent bulb (a reading lamp).
• ~1,500 lumens = bright single-room lighting (our knob-controlled arc at 18W).
• ~2,400 lumens = three independent reading zones at once (the 27W three-light arc).
• ~3,000 lumens = whole-room ambient light (the 30W torchieres).

2. Kelvin: the mood dial

Color temperature (Kelvin, K) decides whether light feels like candlelight or a dental clinic:

• 2700–3000K — warm white. Evenings, TV rooms, bedrooms. Matches most incandescent lighting people grew up with.
• 3500–4500K — neutral. Kitchens and desks; honest light for cooking and paperwork.
• 5000–6500K — daylight. Cleaning day, makeup, detailed crafts. Also the setting that makes a room feel awake on a gray morning.

Adjustable models (like our table lamps at 3000K–6500K) carry both ends in one lamp and shift by remote — warm for the movie, daylight for the cleaning.

3. Dimming: stepless or stepped

Stepped dimming jumps between presets; stepless dimming slides continuously from 0 to 100%. The difference shows up at night, when you want 15% and stepped dimming insists on 25%. All our floor lamps dim steplessly and flicker-free — flicker matters more than most people realize for evening eye strain.

4. CRI in one paragraph

Color Rendering Index (CRI) measures how true colors look under the light, on a 0–100 scale. Anything above 80 is fine for a living room; photographers and painters chase 90+. We publish the specs that are measured and listed for each model — check the specification table on the product page rather than trusting marketing labels.

The 60-second spec checklist

1. Lumens ≥ your room's need (anchor list above).
2. Dimmable, stepless, flicker-free.
3. Color temperature fixed-warm or adjustable — decide by how you use evenings.
4. LED included, ETL listed, US-spec plug.
