Feit Electric LED A21 Warm White 4-Pack

These A21 LED bulbs solve the energy waste problem that traditional incandescents create. With two distinct options — a 100W equivalent drawing just 17.5W and a 200W equivalent using only 25W — contractors get serious light output without the power draw.

Skip them if you’re married to old-school incandescents or need specialty lighting. These shine in general-purpose applications: table lamps, ceiling fixtures, workshops, and anywhere you need reliable, bright light that won’t spike the electric bill.

Energy Efficiency That Actually Matters

The numbers tell the story. That 200W equivalent delivers 3,050 lumens while sipping just 25 watts — a remarkable 122 lumens per watt. Compare that to the 100W equivalent at 91.4 lumens per watt, and you see why the high-output version makes sense for commercial spaces.

Both versions cut energy use dramatically — 82.5% savings on the 100W model and 87% on the 200W. In Montana, where winter days are short and lights run long, those savings add up fast.

Lifespan varies between models. The standard 100W equivalent runs 15,000 hours, while the high-output 200W version extends to 25,000 hours. That’s 10 to 25 times longer than the 1,000-hour incandescent you’re replacing. Fewer ladder trips to remote fixtures — that alone justifies the switch for most contractors.

Professional Features Worth Noting

The 100W models deliver 90 CRI — that’s color accuracy that matters when you’re matching paint or showing product displays. The 200W version drops to 80 CRI, a reasonable trade-off for maximum light output in utility spaces.

Both versions use standard E26 medium screw bases and fit A21 fixtures. The form factor is slightly larger than standard A19 bulbs, so check clearance in tight fixtures. All models handle damp locations — bathrooms, covered outdoor fixtures, anywhere moisture might be present.

The 100W versions offer dimming capability, working with most modern LED-compatible dimmers. The 200W high-output model doesn’t dim — don’t put it on a dimmer circuit.

Features that matter: instant full brightness (no warm-up time), mercury-free construction, low heat emission, and shatter-resistant frosted polycarbonate lenses. Some models include selectable white options, letting you switch between color temperatures.

The three-year limited warranty covers manufacturer defects with replacement as the typical remedy. Keep your receipts — proof of purchase is often required.

Users rate these bulbs highly at 4.8 out of 5 stars, praising the bright output, good dimming performance, immediate light with no flicker, and affordable multi-pack value. The main complaint: some variations like the 200W version don’t dim, and availability can be spotty.

Frequently Asked Questions

What’s the real difference between the 100W and 200W equivalent models?

Beyond the obvious brightness jump from 1,600 to 3,050 lumens, the 200W model offers better efficiency at 122 lumens per watt, longer life at 25,000 hours, but sacrifices dimming capability and drops to 80 CRI. Choose based on whether you need maximum light or dimming control.

Do these bulbs work with existing dimmer switches?

The 100W equivalent models are dimmable and compatible with most modern LED dimmers from brands like Lutron and Leviton. The 200W version is non-dimmable and should never be used on dimmer circuits.

How do these handle Montana’s temperature extremes?

These bulbs are rated for damp locations and indoor use, suitable for enclosed fixtures on select models. They’ll handle typical indoor temperature ranges and covered outdoor applications, though they’re not designed for direct weather exposure.

Which color temperature works best for different spaces?

The 100W models offer both 2700K soft white and 3000K warm white options, while the 200W only comes in 3000K. Use 2700K for living spaces where you want warmer light, 3000K for kitchens, workspaces, and anywhere you need crisper illumination.
