Review: Bright, efficient and perfect replacement bulbs - These DUMILOO G4 LED bulbs are fantastic! They’re incredibly bright for their size, and the 6000K daylight white gives a crisp, clean light that instantly improved visibility in my fixtures. They were super easy to install—the bi-pin base fit perfectly with no issues. I also love that they run cool and use far less energy than the old halogen bulbs. No flickering, no buzzing, just steady, reliable light. Whether for under-cabinet lights, accent lighting, or RV fixtures, these bulbs are an excellent upgrade. Great quality, great brightness, and great value. Highly recommend!
Review: Excellent quality, appearance, lumination and price point - I initially ordered these just to try them out, as I needed something brighter than the typical 20 watt equivalent LED's. I use them for certain areas of the landscaping including path-lights and around the deck. They are indeed brighter and the description of 2700k/450 lm is accurate. They appear to be top quality and just as high in quality or better when compared to others that I have tried such as Bulbrite. Although the warranty period on these is shorter, they are also much less expensive. I like them so much that I ordered them two more times after my initial purchase just to have some extras on hand. I cannot speak toward longevity at this time but they appear to be durable.

## Questions & Answers

**Q: Suche led leuchtmittel 3w ac 220v**
A: They are 12V,Thank you.

**Q: I have a  2 light ge profile range hood that has three brightness settings, low-medium-high. will these bulbs work in my hood?**
A: Hi,

Without knowing which model hood vent, I can't quite answer your question.  Normally these LED bulbs are used in place of 12V halogen bulbs used in landscaping applications (at least this is where I used them).  Don't know if the lighting in your hood vent is 12V.  Might be good to check your owner's manual for exact replacement bulb.

Sorry I couldn't be more help.

**Q: Which led bulb replacement for simba halogen bulb is the same size as the simba g4, t3? what is t3? other led's tried; too tall/wide for the housing.**
A: i think best choice is go to home depot and find which number works for you then come to amazon for ordering

**Q: The product descriptions states 2700k while the details states 3000k. These are two different and quite noticeable specs. Which one are they?**
A: I noticed the same thing.  In actuality the bulbs are closer to bright white (3000k) as opposed to the warmer 2700k color.
Hope this helps.
