5.0 out of 5 stars Best Home Light Bulb Out of Many Tested, February 27, 2010
This review is from: Full Spectrum Light Bulb - ALZO 45 watt Compact Fluorescent CFL - Pack of 4 - 5500K- 120V - ALZO Joyous Light daylight pure white light (Electronics)
I am an engineer who has been completely disgusted with the home lighting situation. There are no standards and many misstatements and counterdictions at the stores. I own a Minolta flash meter which accurately measures a lights color temperature. I've tried the bulb technology at Walmart, Sams Club Home Depot and Lowes. The most glaring examples:
1) yellow light is called soft white (2700)
2) very blue light is called daylight 6000-6500)
3) 12W LED lights go for as much as $90!
4) Some bulbs are advertised as white but the chart on the back shows its yellow. Complete incompetence.

Here is not what to avoid: all (harsh washed-out blue) daylight, and (yellow) soft white. While GE Reveal offers somewhat better clarity its still overpriced and quite yellow.

Full spectrum (5000-5500) bulbs are a step-up but stores offer a very limited selection, like one! The Home Depot full 100w spectrum's beats the Lowe's Ott-Lite. The best compromise are the PAR38 indoor 23-27w 3500K reflector lights (which actually measure 4100K), especially for recessed kitchen spot lighting.

On the LED front Sam's Club carries a 520 lumen, 4100K, 9 LED PAR38 reflector which has a easily noticeable smoother light spectrum. Interesting for the one light on in the kitchen in the evening. The equivalent $70 LED lights at the hardware store are hardly a bargain, as the Sam's is $20! However its Color Retention index (CRI)is only 74.

The best of all are lights are these 5500K Alzo's. I've installed a 45w in the kitchen pantry and the color of the food boxes really pop. Food looks like it does in the magazines. The clarity is first rate (however 27w should be sufficient). They are the reference to which others are to be compared. My wife has not complained even when they are on at night-time. This is a first.
Skin tones in the bathroom look very natural. A first again.

Color temperature alone is not the sole basis to buy a bulb as a high CRI is also required. The Alzo's come in at 92, which is very high. Most manufactures do not even list this measurable figure (assume because its too low).

Well gotta go as my wife wants one in her closet now, as shes hates the other fluorescent lights which cause eye-strain. Should I install a 45w and blow her away?

I've been testing more bulbs. For vanity and lamps these offer a VERY uniform ball of nice white 5000K glow. I ordered 12 for my new house's bathrooms:
Maxlite 14 Watt G30 Globe CFL DL SKM14EGDL

For kitchen these are now the best 5000K PAR lights. Not as high of color quality as Alzo, but they don't make reflector lights!
Maxlite 23 Watt CFL R40 Flood Day Lite SKR423FLDL

Further testing indicate a new best-buy, as the colors really pop indicating a very high CRI. Search for "Honeywell Bright White". Available in 14w and 23w for $3.50 bulb.
The manufacture quote is true:
"Your customer won't have to wait for a clear afternoon to enjoy a bright, soft and smooth light! Not only will everything look better, but you will get a 100 watt equivalent bulb that uses only 23 watts."
1600 lumens is impressive too. Found mine locally at Big Lots. Not to be missed.

NotaSecondTime... THANK YOU for the original review, and your extremely helpful updates, as well. This is EXACTLY the information I was wanting! I too have tried lots and lots of bulbs, and have been unhappy so far. I am looking forward to trying your suggestions!

The Honeywell link is dead, and it looks like they discontinued the product.

NotaSecondTime, any updates, or a new winner?

Thank you for this excellent and helpful review. Do you have anything to say about the buzzing sound some reviewers are mentioning? That's something (potentially) that would quickly get on my nerves.

Is this the product? Honeywell 23 Watt Brite White T2 Mini Spiral, 3-pack CFL Light Bulbs

lynn, the buzzing is very faint and can be easily drowned out by any other ambient noise in the room like a small fan or refrigerator running.

For me I have to stand a foot from the Alzo 45 watt/150 watt incandescent equiv. version to hear it. It's about almost as loud as a nat or fly buzzing by your ear. Stand several feet away and you can't hear anything.

I think I would agree with Tim L.'s assessment of the buzzing sound; it is audible, but not loud. However, the noise is noticeable enough that I only use these in my basement, where I don't notice the sound. The light it puts out is great, and I do wish these were silent, then I could use them everywhere. Anyone know of a similar light that is silent?

Thanks for a comprehensive review. Someone else mentioned loud hum coming from this bulb. Can you comment on that?
