Review on 💡 CBconcept 10XG412V10W G4 JC Halogen Light Bulb, 10-Watt, 12-Volt, Pack of 10 Bulbs by Sarah Codina

I used 60 of these lights to retrofit the old (dim and high wattage) lights in my boat to improve the efficiency of the LEDs. Before I decided on this one, I tried different variants of the brand. I am very happy with the CBConcept versions as they are of very high quality and match exactly any color balance you need. (I tested 6000K, 4000K and 3000K). Between the different color temperatures, I ordered probably 90 of these bulbs and they all worked. None of them have dead LEDs. The price per bulb is excellent for the quality you get. They have been installed for about 7 months of heavy use with no problems. A little technical information about the project for those interested: Each dome in my boat had two small bulbs that turned on individually. (This is a 12V DC system). With both bulbs, they drew just over 2 amps and put out about 300 lumens. For human reference, a typical 100W household incandescent bulb produces about 1600 lumens. In our salon/kitchen we have 7 lights. So with all the lighting we'd be pulling a pretty hefty 14 amps into the living space and it might still seem a bit dim (all 7 lights combined only putting out about 1 and a third of the 100 watt bulbs for the entire space) during the house bank was drained somewhat aggressively. We also have AC lamps, but we don't spend much time connecting to the mains. We rely on solar energy. I gutted the old lights and wired them up with an ON-OFF-ON switch wired as LOW-OFF-HIGH. 2 low-power CBConcept lamps, all 4 high-power lamps. The rectangular LED lamp in the middle is a red block that is connected separately. Checked with a handheld multimeter. Thus, each dome (on HIGH) now consumes about 1/3 the previous amount and puts out 4 times as much light. Even at LOW, the lights deliver more than twice the previous maximum lumens while consuming 1/3 amps instead of 2 amps. totally unnecessary. At the port, when we had guests, we just plugged in to turn on the air conditioner light so people wouldn't think we were living like trolls in a cave. Now a 12 volt system is more than adequate. In the main cabin, that means almost six 100-watt bulbs, while now only drawing 4.2 amps. About color temperature: for those who care about color temperature. I started the project thinking I needed 4000K bulbs because I tend to put on bright/clear light. Surprisingly, 6000K gave a very dim light from all the lamps I tested. I think it makes sense because blue light scatters more easily than red light, but I was still shocked to see the effect indoors. In fact, I thought my eyes were a little cloudy from being dry and that I needed to drink some water. The 4000K bulbs were very clear, but apart from looking very harsh in our interior, all the wood looked a very odd yellow. To clarify, there was nothing wrong with the color of the bulbs, I just didn't like the interaction with our interior. 3000K was perfect and (for me) much whiter than incandescent bulbs. All of this is just to say that even if you think you know the color temperature you want, for a large project I recommend testing each color in space before buying them all.
