12Vmonster DC 12V 6 Watt Warm White 2700k LED Edison Filament A60 A19 Light Bulb E26 E27 Medium Base Lamp DC 12V 24V 36V Camping RV Cabin DC Battery Bank System Lighting Tesla Powerwall Motor Home PV

I use these in my off grid cabin, they work great, give off plenty of light, and run directly from the battery bank, no need for an inverter.

I was looking for a warm soft led bulb. This one lit up the front yard. It's a good sturdy bulb but was too bright.

This bulb is advertised as dimmable, but it is NOT actually dimmable. It dims from 100% down to about 90% brightness, then cuts off to 0% for the entire remainder of the dimmer's range. And, within that tiny range of slight dimming, it emits a noticeable, high-pitched buzzing sound when set to anything lower than 100%.The dimmer I tested with is a high quality 12V PWM dimmer meant for LEDs. Other 12V LED fixtures I use this exact dimmer with dim completely smoothly through the full range—no flickering, no buzzing—from 100% brightness all the way down to 0%. So, I was quite disappointed, as I was hoping for the same dimming performance from this bulb.The bulb would be okay for a low-brightness, accent fixture if you do not plan to use a dimmer.My only other comment is that it appears to be significantly warmer than 3000k color temperature (not a complaint, just something to be aware of).

I Loved the size, look and brightness of these bulbs. I have had them a pretty good while using them intermittently with no issues. However when I installed an outdoor lantern that is open on the bottom (Not fully enclosed) and I've had two failures in as many months. They are switched on and off with a relay timer and supplied with 12VDC. The fail mode is that they will get dim and then brighten back up for a few days then just barely glow. Even when I put them on 24V it didn't change the luminance much that I could tell. I really had high hopes for these lamps.

Ordered 4 lamps one was damaged from shipping. However the Amazon returns is easy and quick through Kole's. The 3 lamps are nice and bright from 12vdc to 25vdc. They are dimmable as I used a 1 amp variable dc power supply to test. A 9v radio battery will light up these bulbs. ( for a quick test) full brightness comes on at 11 vdc and stays consistent up to 25vdc. My power supply is limited to 25 vdc. The current is higher at lower voltage around 900 ma. At 5vdc. And as voltage increases the current lowers way down to 90ma at 25vdc.

INITIAL IMPRESSION: This is the best thing to happen to lighting technology since Edison and Tesla! These bulbs have all the advantages of old-world charm with none of the disadvantages of tungsten filament lighting. They are beautiful, functional and above all, EFFICIENT! We especially appreciate the 2700 K color temperature, which only adds to their old-world charm.HOWEVER, be warned: only time will tell if this product has or has not fallen victim to the ever-present evil of engineered obsolescence. We will know that is true if they fail to function properly for at least a decade of normal household use.

I've just completed measuring several of the 12v LED bulbs at Amazon, and of all of the bulbs (including other COB), these drew exactly the amount of current as they were rated (6w). The light was also more than any of the others I tested (3.5 -- 7w range). This bulb will dim as well. Very nice, but a bit on the expensive side.

Manufacturer claims these are dimmable but they are not. They replaced bulbs that were dimmable and the old ones dimmed fine. The switch is not the issue. These look like strobes when dimmed, flickering like crazy. At full brightness they are nice, warm light.

If you want a bright 12 V bulb this is it. I took the pictures well after dark. It is almost too bright for me as there are five bulbs in a small area. I would still rather have too much light than not enough. The product definitely exceeded my expectations.

Bought for someone, so I cannot say much, but they looked to be alright for the job...

Wir verwenden diese LED-Glühbirnen in unserem Glühbirnen fressenden Kronleuchter eines bekannten Designers, der mit 24 24V-Birnen bestückt sein möchte. Der Verbrauch der regulären Ersatzbirnen lag bis dahin bei 10 - 15 Glühbirnen; das geht bei 11 € pro Stück ins Geld.In den 8 Monaten, in denen wir diesen Glühbirnen verwenden, hat noch keine einzige versagt. Verglichen mit den herkömmlichen Halogenbirnen 10 W / 15W sind diese Birnen sehr hell und das Licht wird zumindest anfangs als kalt empfunden. Aber daran gewöhnt man sich. Wenn man sich an den deutlich sichtbaren LEDs nicht stört, rundum eine Kaufempfehlung!

Die Filament-LED ist soweit ok.Ich nutze diese Lampe in einem kleinen Gartenhäuschen. Hier ist mir das Licht noch etwas zu weiß.Das ist aber auch ein wenig Geschmackssache.

Lampada efficiente con poche wat fa una luce eccezionale, fino a oro non avrei mai creduto che una lampada a filamento Led facesse una luce così.
