CBconcept10XG412V10W G4 JC Halogen Light Bulb,10-Watt,12-Volt, 10 Bulbs

I used 60 of these to convert the old (dim & watt hungry) fixtures in my boat for LED efficiency. I tested out a number of brand's options before settling on these. I've very happy with the CBConcept versions because they are very high quality and come accurately in whatever color balance you need. (I tested the 6000K, 4000K, and 3000K). Between the difference color temperatures I probably ordered 90 of these bulbs and they all worked. No dead LEDs in any of them. The price per bulb is excellent for the quality you receive.They've been installed now for around 7 months of heavy use with no issues.Some slightly technical information about the project for those who care:Each dome fixture in my boat had two small incandescent bulbs individually switched. (This is a 12V DC system). With both bulbs on they drew a bit more than 2amps and put out around 300 lumens. For reference in terms people can relate to, a typical 100W household bulb puts out around 1600 lumens. In our saloon/galley we have 7 fixtures. So all lit up we would draw a fairly heavy 14 amps in the living space and it still could seem a bit dim (all 7 fixtures combined only put out about 1 and a third 100w bulbs worth of light for the entire space), while draining the house bank somewhat aggressively. We have AC lamps too but don't spend much time hooked up to the grid. We rely on solar.I gutted the old fixtures and rewired them with an ON-OFF-ON switch wired as LOW-OFF-HIGH. Low powers 2 of the CBConcept bulbs, high powers all 4. The rectangle LED bulb in the middle is a red unit, wired separately.Now, on HIGH, each fixture puts out 1280 lumens while drawing 2/3 of an amp, which I've verified with a handheld multimeter. So each dome (on HIGH) now draws about 1/3 of the previous amount while putting out 4 times as much light. Even on LOW the fixtures put out more than double the previous maximum lumens per fixture while drawing 1/3 of an amp instead of 2 amps.This change is significant enough that we are now in the process of removing all the AC light fixtures because they are completely unnecessary. In harbor if we had guests over, we used to hook up to the grid just so we could run the AC lights to prevent people from thinking we lived like trolls in a cave. Now the 12V system is more than adequate.In the main cabin this translates to almost six 100w bulbs worth of light output while now only drawing 4.2 amps.On Color Temperature:For those wondering about color temperature. I started the project thinking I would want the 4000K bulbs because I tend to light sharp/clear light. Surprisingly, 6000K in all the bulbs I tested cast what I felt was a very hazy light. I guess this makes sense, because blue light scatters more readily than red, but I was still shocked seeing the effect indoors. I actually thought my eyes were a bit hazy from being dry and that I needed to drink some water. The 4000K bulbs were very clear but, in addition to seeming very harsh in our interior, made all the wood look very oddly yellow. To clarify, there was nothing wrong with the color of the bulbs, it was just interaction with our interior that I didn't like. The 3000K were perfect, and (to me) much more white than the incandescent.All that is just to say that even if you think you know which color temperature you want, if you are doing a large project I recommend testing each color in the space before buying them all.

If these were available in 4500K I would give them 5 stars. The 4000K is slightly yellow compared to the 4500K tone. This is my second set. As the old, much more expensive LED's (4500K), fail I am replacing them with this product. Good value and long lasting. The use is for my RV ceiling lights, about 20 of them. This replacement bulb is now in 10 lights in the main room. Bright but a bit hard on the eyes for my taste. There is no other good, affordable LED I have found on the market. The next available color temperature in G4 base is 5000K or 6000K. Much too blue.

Problem: you have some LiPo battery pack (from radio-control plane/quadcopter/car...) that is damaged and puffed. That's a fire hazard.So you need to discharge it to 0 Volts, then it can go to the trash. (why there is no way to recycle Lithium is another problem)Get a bag of sand from the hardware store, stick the battery in it with only the wires coming out. put one light across the terminals (works great with XT-60, no need to build an adapter), let it plugged for a couple of days. All of that outdoor far from any structure, and not in a place that can get fires. Check what is ok... one could put that inside a grill as a safe place).disconnect, check the voltage, if zero, discard according to your local garbage rules.So the cost is minimal, and the result is good for that usage.

Purchased this hoping it would be a "white-white" lamp. It is more like a 5000K coloring with too much blue. I compared it to another brand and some existing 4000K lamps that I have and the "CBconcept, SidePin LED G4, 320 Lumens, 2 Watt (20W Equal), Soft White 4000K" lamp is definitely more in the range of 5000K and should be advertised as such. This is disappointing and I feel that I wasted money on these.

I bought these bulbs to replace the original halogen bulbs in my microwave cooktop lights. They were 10 watt bulbs that have burned out several times in a 5 year span. Since i have updated most bulbs in my house to LED technology I decided to try them in this application after a recent burnout. These are notably different in appearance than the halogen type but as long as the mounting space was large enough I knew they would work. My light has a 3 step dimming function so I was hoping these would work in this scenario. Well, I can tell you that they do work sort of. They work at 2 different brightness levels but the first setting causes an annoying flickering pattern. Pressing the button a second or third time straightens that out and they work fine. The brightness levels seem to change in an opposite fashion than before. In other words Instead of going from Brightest, bright then dim, they start off with the flicker then bright and brightest. The brightness levels are higher than the previous halogen bulb which is fine except that now the night light function is too bright for my taste. I'm not sure I can fault these bulbs for the odd behavior as I know some light fixtures simply were not meant for LED bulbs to start with and I have had similar experiences with LED bulbs and dimmers in other applications. Your mileage may vary but in the end I am satisfied with the results and I expect these to last much longer than the halogen bulbs they replaced and consume less energy which was my main goal..

De 5 focos, ya solo quedan 3. Primero falló al mes y el segundo a los 3 o 4 meses. Muy poco confiables3 semanas después ya solo me quedan 2 de los 5. No los recomiendo para nada

Packed and shipped properly and on time as promised. I don't know enough about halogen bulbs to know the difference between them, they appear to be the same I had and they work.

Watts up? These bulbs arrived on time and fit my fixtures well. No complaints at all.

very good quality, a bit more expensive than other bulbs with no brand, but for the reliability and quality, worth it. and compared to Home Depot $5.95 each bulb, man you save a LOT

Overall good value when compared to the price of these bulbs at other retailers, but two broke while I was trying to install 8 bulbs, so maybe the physical quality of the bulbs aren't that great. Time will tell the tale about the lifespan of these bulbs.
