ALIDE G9 Led Bulbs Dimmable 3W Replace 20W 25W 30W Halogen Equivalent,2700K Soft Warm White, AC120V G9 Clear T4 Bi-pin Led Bulbs for Chandelier Pendant Wall Home Lighting,300LM,360 Deg,10Pack

I ordered these LED bulbs to replace 15 halogen bulbs in a chandelier with a dimmer switch. At full power, the old halogen and new LED bulbs were nearly identical through the frosted bulb covers. When dimmed, the LED bulbs were whiter, but it really didn't matter since they still looked great and I was replacing all halogen bulbs. The old halogen bulbs were only rated for 2000 hours, which is far less than these LED bulbs. Dimming worked exactly as expected. They've been in use for a couple of weeks, no failed bulbs, energy consumption is down, and we shouldn't have to replace another bulb for years. All the halogen bulbs were replaced with LED for about the price of five halogens. Note the bulb dimensions, they're slightly taller than a typical halogen, but it didn't matter for my application. I'd absolutely order them again.

Definitely should have a dimmer !

Obviously they work and great color which was what I was mostly focused on (the warmth) but they don't last long - they start burning out after a year, nowhere near 30,000 hours.

First, they aren't 2700K. They fall into the 3000K+ range a bit. However, they dim in both variable dimmer circuits and High/Low lighting appliances (High/Low is achieved by the use of a diode on the low toggle, which effectively provides half of the A/C waveform. That's called half-wave rectification, and from a 120V A/C source, you get 60 volts every other cycle to the bulb). That last bit is what causes "flicker" in other LEDs you'll find. These do have a nearly imperceptible flicker, which means the manufacturer took additional precautions to add sufficient capacitance to make up for the drop every cycle. The result is a "Low" that is not really half as bright as the "High" but does produce a dimmer light. So, for example, if you have a microwave oven light that's one of those High/Low toggles, this will be perfect for that application. Many under counter fixtures use the High/Low toggle as well, and these will work well in them (again, don't expect half the light). You probably won't notice the very, very slight flickering (again, nearly imperceptible). If you have an in-line dimmer, these really do a fantastic job of full-spectrum dimming. These DO NOT "warm" as they dim. They weren't advertised to, either; but it's a common expectation with bulbs that are being dimmed. There are LED products that produce a warmer glow as they are dimmed. Philips puts out some, for example. I hope this helps clarify not only how the dimming is accomplished in High/Low applications, but also gives a big thumbs-up for these (they're a bit pricey, compared to their peers, but are worth the extra bit).

Arrived early. Great for price!
