Not Just Good,but Great Recently I’ve been on an LED lighting kick. I believe that after a little experimentation I’ve found what will be my “go to” bulb for general purpose, indoor use. Now, after testing this Feit flood light, I have finally found an LED flood light that is far brighter than the CFL flood light and the 100 watt halogen flood light I had been using.Claimed brightness (lumens) and incandescent equivalent claims have been an area that has been lied about more often by LED manufacturers than I can keep track of. I recently bought an LED bulb claiming to be a 60 watt incandescent equivalent (not from Feit) and it’s far dimmer than the 40 watt bulb I replaced. So far Philips seems to be the only company I’ve found that makes good on its brightness claims… that is until I got the Feit flood bulb.I was looking for a good flood bulb to replace the several I have in various weather protected, outside fixtures. We’ve had some CFL (fluorescent) bulbs outside for a while now and they do marginally well in the summer, but in the cold weather, they can take many minutes to warm up and reach their full brightness. The CFL we had in an overhead light fixture above our covered deck had recently burnt out and I had temporarily installed an old halogen flood bulb that we had sitting around. The CFL threw a wide beam, but the halogen was brighter and came on with its full brightness right away. When I installed the Feit flood light this evening and turned it on, I was so surprised and pleased I actually went and got the wife to show her.The light is pleasantly warm, I’d say in the 2700 – 3500 kelvin range (just a guess), and the beam pattern is much wider than the halogen flood and far brighter than either the halogen or the CFL we’d recently had in the fixture. The covered potion of our deck is about 12 feet by 20 feet and the bulb brightly and evenly illuminated the entire area from a ceiling fan hanging about ten feet above the deck surface. Unlike the halogen there was no bright spot in the center of the beam and unlike the CFL, the LED came on with full brightness.As another reviewer noted, LEDs have notoriously high failure rate. Many will last their claimed hours, and many will suffer an early demise. This is an emerging technology and will only get better with time. If you buy your bulb on Amazon, you don’t need to save your receipt because you can just back onto Amazon and print another if you need to return your bulb in the future.After trying many LED bulbs, rating the Feit LED flood five stars is a no brainer. From my experience, right now anyway, it just doesn’t get any better than this.

Impressive I compared this BR40 LED bulb to a BR40 100W incandescent and an equivalent BR40 Compact Fluorescent (CFL) bulb. As an electronics engineer, I understand the limitations of LED technology, and I know how easy it is to be bitten by cheap LED bulbs and bad designs, so I was very skeptical of this one. So far, though, I have been seriously impressed.First of all, its light output is just as bright as a 100W incandescent, and spreads evenly and widely, like a true flood, not a spot. The diffused lens is evenly lit and the individual LEDs inside are not visible. As for color temperature and quality of the light, this bulb comes closer to incandescent than any of the CFLs I’ve tested. CFLs tend to be more yellow, whereas this LED has an ever-so-slightly rosy hue (tending toward red) that is noticeable next to a CFL, but barely noticeable next to an incandescent. (The Feit Electric BR30 LED Bulb is a 65W equivalent that seems too rosy for my liking).The bulb itself is prettier than most LED designs, using a heatsink that is both functional and attractive. Excessive heat kills electronics, so the heatsink must be designed to spread and dissipate the heat well. After leaving the bulb burning for 24hrs in a non-vented recessed ceiling fixture, I removed the bulb to check its temperature. It was too hot to hold indefinitely, but seemed within acceptable limits. Hopefully it has been designed well enough to cope with high summer temperatures, and its power supply components have been rated to last as long as the LEDs. Time will tell.I tried flipping the light switch on and off rapidly to test the robustness of its power supply, and it did just fine. One thing did scare me though: After leaving it burning for a few hours (to reach its maximum operating temperature), I flipped the switch off, then immediately back on. The bulb would not light up, and I thought it had died. For the next hour or two, I kept trying the switch, and eventually it came back on, possibly after cooling down. For a couple of days, I repeated this test, with the same result each time. I assumed it was a temperature lockout circuit at work. That would have been a deal-breaker for me. However, I tried one more thing… Next time the bulb refused to re-light, I left the switch on and walked away. Two hours later, I noticed that the bulb had lit up on its own. Since then, it has never refused to light again, no matter how long I’ve left it on – and no matter how many times I’ve flipped the switch afterward. I’ve used it for 4 months since then. Maybe my abuse had put the bulb into some strange mode. Nevertheless, leaving the switch on, fixed the problem.As noted by others, the bulb takes about a quarter of a second to light up, probably to protect itself from switch contact bounce (or abuse) and to check its temperature before turning on. This is a totally negligible delay. The light reaches full brightness instantly. No warm-up time like CFLs. I am sold on this bulb.
