Hizashi Flicker-Free GU10 LED Bulbs, 94 CRI, 50W Halogen Equivalent, Non Dimmable, 4.5W 420LM LED Spot Light, 5000K Daylight White LED Light Bulbs Recessed Lighting, Track Lighting, UL Listed, 10 Pack

These were the perfect bulbs I was looking for, but it took me three other orders before I finally got the right ones. These GU10 bulbs can be very confusing with four different color temperatures available (2700K-very yellow, 3000K-soft white, 4000K-daylight white, and 5000K-sunlight white) and at least two different wattage powers (4.5W LED = 35W Halogen/400-450 Lumens and 5-6W LED = 50W Halogen/500-600 Lumens). Then there is the beam angle. Some are wide beam/floodlights and others are more narrow beam (40 degrees) spotlights. Also - some GU10 bulbs are slightly longer than others and don't fit properly in certain fixtures. These bulbs were 3000K, 4.5W/450 Lumens, narrow beam and short length which was just what I wanted for my fixtures and the warm white office lighting for highlighting maps and plaques on the wall. Unfortunately, there was virtually no way to figure all this out except the hard way of trial and error. Sure appreciate Amazon and its sellers' free return policy. Now, I'm a happy camper!

Build and quality A+Brightness - true daylightLongevity : I just Installed these but Will update in 3-6 monthsInstallation = plug and playShipping and packaging = fast shipping and double boxed A+Low consumption = 3500k 4.5w compared to My other ones which were 5k 7w (5k is overkill for My purpose which were rooms and hall ways ,unless your using it a bigger area and wanted to have flourescent color hue, 3500k is good for in house application)Seller Communication= A+ these days it all books down to Customer Service as there are alot OF complained that sells the same products...My philosophy and base on experience I would rather Go for seller Customer Service and doesnt matter if its a brand name or new company as long as they can back UP their product thats were I would lean on towards My purchase which in this case, the seller reached out for any problems and or suggestion on their product and to me thats rare. So I have to give them credit for that and an A+ that simple gesture gave that slight confidence that this brand is willing to listen and grow.

The bulbs are exceptionally well made and nicely packaged. Full technical information is provided on the box. I replaced a set of track light bulbs and all the new ones come on and provide light without flicker or interference. The old set required a minimum of one standard quartz halogen high energy usage bulb as a ballast to prevent the LED's from cycling on and off every few seconds. This was a common problem with older GU10 LED's. The Hizashi bulbs do not have this issue and I can rum 8 bulbs in a track without flickering. The bulbs compared side to side with my older GU10's are much more nicely manufactured. The warm white (3000k) bulbs are bright and an provide an exceptionally nice spectrum of light inside a home compared to the cold blue spectrum of daylight bulbs. A+

I have only had these a month but already am hooked. The previous brands were dull, dark and burnt out in 3 weeks even with proper installation using gloves. These r pricier initially but I'm running less light fixtures now as these r bright! Even better, as a senior, not having to perch on a step stool to change out a g10 or two (out of the 10 I use on a regular basis) every 3 weeks is a health benefit!

I love these bulbs. I have really nice ceiling fans with GU10 bulbs. The 50 watt halogen bulbs wasted to much power and would give off a lot of heat. I actually was going to change my ceiling fans until I stumbled across these bulbs. I figured ok let me try them. Well I have to say I am 100% happy with product. These bulbs are so bright much brighter than the 50 watt halogen bulbs. The light shade / color is perfect. I am so happy. Also I emailed customer service with a few questions. They were very quick to reply and they went above and beyond to assist me to make sure I was a satisfied customer. These bulbs are awesome and the customer service is outstanding. Thank you I am so happy with product.

After going through several other brands for my chandelier bulbs and kitchen fixtures, I finally found Hizashi. Save yourself the trial and error and just get these ones if you are particular about high quality lighting. These were the only bulbs I tried that didn't make any buzzing noise and had 90+ CRI for good quality light. The chandelier candelabra bulbs have been installed for 9 months with no failures. Just did the kitchen bulbs and will update if any fail prematurely. As far as I'm concerned, this is the best LED brand out there at the moment.

There is really nothing wrong with these lights but, what I mean, they are more like 35 watt halogen bulbs and not 50's. The light is a yellow color instead of what I thought would be whiter, like the 50's would be. Still they are just great and we like them as they are saving a little more on the electric bill and they do illuminate the area. They are still a great buy and would do it again and put them in my hallway, which I may do and switch the ones in the hallway to where I have put the newer ones.

We are in the process of converting all incandescent and CFL lighting in our home to LED. The Hisashi 10-pack is a good deal as we had quite a few halogen bulbs in my wife's studio that they replaced. In addition to the energy savings, the LEDs run much cooler which saves wear and tear on the fixture sockets. Halogen lamps are quite hot and over time will melt a phenolic or plastic socket (actually they get brittle and crack easily from the heat).We like the flicker-free feature and not that the light from these devices is quite flat, which is a plus for my wife's jewelry studio.We've not had the lamps long enough to rate longevity, but our experience thus far with LED lighting is quite positive with regard to how long they last.
