Bought LED 8w(50W) bulb for range hood, bulbs work fine when turned on to regular mode but don't work on the second setting that supposed to make them a little dimmer. Do I need dimmable bulb or is this an LED issue

Not 100% sure but I suspect the LED replacements exhibit a significantly higher impedance when off, unlike incandescent and halogen.

If you have multiple cans controlled by one switch, try changing all but one to LED and likely there will be no flicker at the lighted switch.

If you leave at least one halogen on the circuit and it still flickers, be sure to comment here and I'll research further.

* Range hood lamps are usually available at hardware stores; Lowe's, Home Depot, or a lighting store. Take the old bulb to store for an exact replacement. There are many different bulbs though these are common for track lighting, etc.
* Note; not all range hoods us Halogen. You will find LED lights starting to show up on hoods. I'm not convinced they are the best choice (LED) for a heated area as LED is an electronic device that is sensitive to heat. Halogen's have another use (used under the hood). They do produce heat as with counter top heat lamps used at restaurants. Though not a lot of heat, you can still feel the warmth from Halogen lamps when turned on High settings.

Aloha, ukeboy57

These Halogen bulbs are inefficient, and run so hot that they often damage the reflector and bulb socket if they are left on too long. Fortunately there is an easy fix for this. At most stores that sell the exact replacement Halogen bulbs (Lowes, Home Depot and others) you will see a selection of LED bulbs on the same display rack that will fit into the same socket the Halogen bulbs use. It is IMPORTANT that you know the code number stamped on the base of your Halogen bulb AND its voltage because some Halogen bulbs are 12 volts and some are 110 volts. If you can't read the labeling on the bulb, look for the wiring diagram usually glued inside the range hood or look in your owner's manual. Once you know your Halogen bulb's code number, look at the packages that the LED replacements come in. There will be a list of Halogen bulb code numbers that the LEDs are meant to replace. The male sockets on these LED replacements will be shaped just like the sockets on your original Halogen bulbs so they will plug in easily. However, just like LEDs bulbs that replace the old incandescent bulbs in your table lamps or ceiling sockets, they have an electronic section included in there base to run the LEDs and it makes the LED bulb slightly longer than the much simpler Halogen bulb. For my stove hood it meant that the bulb would not quite fit into the reflector in the hood. I had to use a Dremel tool to remove a bit of the reflector to get a proper fit. The LED bulb is just as bright but runs SO much cooler and uses so much less electricity that now I can use the range hood as a night light in the kitchen. I never felt safe doing that with the two Halogen bulbs since they ran so hot that they were burning the fixture that held them in the stainless steel hood and were melting the wiring entering the socket base. This upgrade to your range hood is well worth the effort.

I could not turn the bulb, and the rubber glove approach did not work. I unscrewed and removed the middle cover, which meant I could easily reach inside and turn the whole light bulb fixture.

What model range hood do you have? To remove most of the bulbs from a Zephyr hood, wait for the bulb to cool after use. Then rotate the bulb counter-clockwise about 60 degrees (less than a quarter turn) and the bulb should drop down. If you have problems turning the bulb, try the glass suction cup that comes with the hood or a rubber/latex glove grip. Sometimes a rubber jar grip will also work.

The one way to find out your range hood bulb may be to remove one and look at the side/back. The bulbs are labeled. Otherwise, check your manual. Zephyr has the manuals for most of their ranges here: http://zephyronline.com/customer_support . Use the drop-down menu to select your model.

Different hoods use different bulbs. For AK6500, 6536, 6542 Cyclone hoods, purchase type: 4OR 14 mini flood light bulbs. For the AK2500, 2536 hoods, you need to purchase type GU 10 halogen bulbs. For the Anzio models, including the ZAN-E30AS, get a GU-10 50W halogen bulb.

I hope this helps.

Chris, I googled and found this
http://www.plasmaled.com/household_led_light_bulb.htm

probably available at a lightbulbs unlimited or other lightbulb store.
Maybe even a Home Depot or Lowes.

Saint...first...have a look at the bulbs. Make sure the bulbs are 'really' good and that the sockets are clean inside and undamaged. Second, the switch might be bad.
