Full Spectrum CFL Light Bulb - 40 Watts (Compares to 150 Watt Incandescent) Review

Average Reviews:

(More customer reviews)I don't like my lights yellow, I don't like them blue. With that in mind, I bought just one of this CFL to check out. It has just a shade of that warm white (5000K instead of 5500K) to it which makes it ideal to use in a residential environment. Pictures taken using a digital camera under this light have come out nice looking - not bluish or yellowish. The difference in color rendering is also clear. So far the lamp hasn't had a high pitch whine which some of the other CFL's have been prone to.
The one thing keeping me from rating this lamp higher is slow startup. Takes at least a couple of minutes for the lamp to reach full brightness. For a 40 watt lamp, it also seems to emit slightly less lumens - but I gladly accept that for better quality light (Quality over Quantity).
Another thing to keep in mind that the lamp is fairly large (tall). This is after all a 40W CFL. Not all fixtures will accept this light w/o the lamp sticking out.
Beats the junk they sell in warehouse stores..

These bulbs are the highest quality full spectrum light bulbs available today. Excellent for reading, they give you true color and superior clarity when compared to standard bulbs. Most compact fluorscent bulbs are not bright enough when compared to incandescent bulbs. This is because they are usually around 2700K color temperature. Our compact fluorescent bulbs are "Full Spectrum" or "True Daylight". This means that they are 5000K. This makes the light more like the color of true sunlight. Full Spectrum lighting is better for reading or anywhere you need to have bright, hight quality lighting. All of our compact fluorescent bulbs have an expected life of 10,000 hours, and save you energy too. Fluorescent bulbs use only a quarter of the energy of an incandescent bulb and they last 10 times longer. Ecological and Economical and great quality of light. It doesn't get any better than that !

Feit Electric ESL40TN/D 42-Watt Compact Fluorescent High-Wattage Bulb, Daylight Review

Average Reviews:

(More customer reviews)The 40W fluorescents (150-200W equivalent) are hard to find in most brick and mortar stores (they like to sell the smaller 40W and the 100W equivalents) so I was double-happy when I saw this one at Amazon. First, because Amazon carries it and second because it's available under super-savers' shipping.
Talking about the item itself:
- you WILL experience some delay when you turn it on but it's hardly noticeable, like maybe 1/10 of a second
- once it's on, unlike the 'cheaper' fluorescents that need to warm up, it shines at or close to full brightness immediately
- it's a bulky, significantly wider and longer than the 150W incandescent equivalents and it may not fit all fixtures where a regular 150W bulb used to fit
- does not work well with a dimmer - it's either on or off [I tried it with one and it did come on at full brightness but something is telling me that you may shorten its life when used this way]
- the light is bright, so bright, I would not stare at it directly - I did once and I saw 'ghosts' for the next 15-30 minutes
- the color of light is closer to 'solar' than what our 'incandescents' deliver, less yellow, more blue
- unlike neon lights, there's no flicker
- it consumes less power when compared to an incandescent
The above were my subjective comments. Here are the specs, as the manufacturer lists them:
- Light output: 2800 lumens
- Energy used: 42W
- Life: 8000 hrs.
- Color temperature: 6500K
- Electric charge: 610mAThe major issue I have with the fluorescents is their lifespan. Maybe I am unlucky but, after replacing nearly all my light bulbs in the house - a few dozen - they seem to burn out more often. My first couple 40W I bought a few years ago (a different brand), in fact, died after about one year, I hope this is not the case again because we are paying top dollar for these environmentally nice devices.
So far, I see no reason not to award this bulb 5 stars but, if it dies on me before 2-3 years, I promise to come back and update my review. For the record, the maker promises a 7-year lifespan and $152 (???) savings per bulb.

January, 2011 update:
On their 20th month, they (I bought a 2-pack) are as bright and shiny as on 'day one' and they've been on for many hours because I telecommute most of the time and my office is in the basement. I haven't done the math but it's likely that they've paid for themselves already.
I bought 2 more in December, 2009 and no burnouts yet.

ALZO Digital Full Spectrum Light Bulb - ALZO 45W Photo CFL 5500K 91 CRI, Daylight balanced, pure white light, 2800 Lumens, Case of 4 Review

Average Reviews:

(More customer reviews)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 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!

ALZO 45-Watt Photo CFL Full Spectrum Light Bulb Review

(More customer reviews)I am a painter of the 'visual art' variety. I use these bulbs in my artist lamps and they are wonderful. Gone are the days of painting at night then discovering in the light of day that my colors are all wrong! Also they are great for lighting my paintings for photographing them. These bulbs are really pretty tough...I knocked a lamp over and the bulb did not break,whew!

GE 13-Watt Energy SmartTM - 8 Pack - 60 watt replacement Review

Average Reviews:

(More customer reviews)At a little over 10 bucks for 8 of these, you can't go wrong.
These are just your basic CFLs, at the 2700 kelvin temperature range. That means they're about the same shade as your basic ordinary 60W incandescent bulb. A pale yellow white, not pure white (5100 Kelvin), or daylight (around 6300 Kelvin).
Pure white or daylight CFLS cost more because the phosphors in them are more expensive, but they do have the advantage of being more natural light, rather than imitating the poor quality light of an ordinary light bulb.
So if you're thinking of upgrading to CFLs these bulbs are a great deal to start from. But do take advantage of the technology & get a higher quality light at a higher color temperature for some of your areas, & enjoy better quality light, rather than just using CFLs that imitate the poor quality light of old fashioned light bulbs.
Winter depression can be triggered by lack of natural light because of less hours of daylight, & more cloudy, overcast days in winters. In northern climates when it's cold, people stay inside more, use heavy insulating window curtains, further reducing their exposure to natural light. 5100K-6700k CFLs help with winter depression by exposing you to more natural light. Colors look more rich & vivid. Things look more cheery. It's even easier to read under natural light.
I find I can read just as easy under a 4-watt 5100k CFL than a 13 watt 2700k CFL.
The backlight in your LCD display that you're probably reading this from is probably a 5100k-6700K bulb.
Look at the white areas on the screen & then look at your lighting in the room. Doesn't that ordinary light bulb or 2700K CFL look a lot more yellow by comparison?
