The product is as white as it promised, which doesn’t surprise me with this kind of price. The only problem I have is that one out of 12 light bulbs I bought is a defect without any external damage. I think they need to improve their own QC with so much at stake. With this kind of of price, I’d expect them to have every single one to be perfect, or I’d rather pay $1/bulb for a regular one that my wife thinks its yellowish light is even more romantic than the totally white one.

If you are looking for Full spectrum, pure white or a reading light that is easy on the eyes… Alzo is it! Instead of trying to explain it just look for the picture, it says everything. I have attached a picture of 3 different so called White lights or full spectrum lights. I wont tell you what the other brands are but the Alzo is the white one.

We couldn’t beat the price for these bulbs. Much cheaper than the single bulbs sold in bird magazines and on popular parrot websites. They are just as advertised. One bulb lights a 15×20 room (enclosed Aviary) in our house. Living in western Washington State, where it is overcast most of the year, even in summer. I have seen a marked improvement in my birds in the past few weeks after replacing the CFL light bulbs with the Full Spectrums.

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 washed-out color light is called daylight (6000-6500)
3) Low lumen (400-600 lumens) LED lights go for as much as $90!
4) Some bulbs are advertised as white but the chart on the back shows its yellow. Go Figure!
Here are the bulbs to avoid: all (harsh washed-out blue) daylight, and (yellow) soft white. The GE Reveal offers somewhat better clarity, but is overpriced and quite yellow.
Full spectrum (5000-5500) bulbs are a step-up but stores offer a very limited selection. The Home Depot full 100w spectrum’s beats the Lowe’s Ott-Lite.
On the LED front Sam’s Club carries a 520 lumen, 4100K, 9 LED PAR38 reflector which has a easily noticeable smoother light spectrum. Great 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).
I’ve been testing other bulbs. For vanity and lamps (Alzo does make any) 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
In summary best home lights are the Photo CFL which offer both a 5000-5500K range with a CRI over 90. Further these bulbs allow for brighter rooms, as compared to hardware store types. That is, the more pleasing light allows for greater brightness levels, so go for the 45watt bulbs in larger pantries or rooms.
Thanks go to Amazon and Alzo for allowing consumers to purchase superior quality products at a price no higher than the unpleasant and unsatisfying bulbs in the store. Hope this helps!

these bulbs are awesome. pure white light. no blue, no yellow, just pure white. i also ordered the 43 watt alzo bulbs and although they are rated at double the lumens i prefer this size. it seems to give almost as much light output while being 1/3 smaller and using about 40% less energy.
they are slightly pricey considering u can get a ‘bright white’ 4100k 2 pack of 26 watt bulbs for 6 dollars at home depot, but these give slightly better light for those that need pure light to show details. such as photography, autodetailing, woodworking, painting etc.
