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

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.

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.

Been using these for a while in my RV and they work well. Put off lots of light, I would almost say too much light as I was looking for more of an Edison glow but they have been great bulbs.

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.

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.

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.

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.

I have this installed outside in a streetlight style enclosure for about 9 months. It is powered off my landscape lighting transformer. It has held up in extreme heat and cold, and naturally it is installed in a "damp" location. If if were to break at this point I would not hesitate to order another.

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.

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!

Aspettate per tanto tempo ma non servono a niente usate un paio d'ore e poi si sono subito fulminate 29 euro buttati al vento . Così non va proprio alla fine a comprare online ci si rimette 😕

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

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.
