I purchased this on 2 separate orders, and both times the cardboard/plastic package around the bulb was open and the bulb was loose in the[Amazon] box.They did work however,and provide a beautiful warm light in my mica desk lamp.I would give the bulb 5 stars and the packaging 0, if I could.I hope if Amazon gets in a new shipment of these the problem will have been corrected as I would like to order more.

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

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

7W LED Incandescent Replacement Light Review

7W LED Incandescent Replacement Light
Average Reviews:

(More customer reviews)
I rarely write reviews but I felt compelled to write one for this product. I purchased this 7W LED bulb one month ago. Being an engineer, I spent a great deal of time reviewing LED bulbs before deciding to purchase this one. Before I provide my review of the LED bulb, I want to provide some clarification. Having read the other reviews where some people said that they received something different than what was pictured, I decided to e-mail Priority Energy and Lighting before I placed my Amazon order. I was pleasantly surprised that Paul Prior, the CEO and president of Priority Energy and Lighting e-mailed me back the very next day. He told me that they used to sell the frosted globe that is pictured above but he said that most people preferred the clear glass. Paul also said that I could still order the frosted glass version but I would have to go through their system and not Amazon's site. He said that the frosted version available through their system is 2,700K (yellow, warmer color, typical color of incandescent, and frosted). If you are interested in purchasing the frosted version, you can contact them at priorityled DOT com. I agree with other people that the photo of the LED bulb on Amazon's site should match exactly what people are going to receive. In the product description, they could let people know that the frosted version is also available but you have to go through Priority Energy and Lighting directly to purchase the frosted version.
Ok, now to my review of the clear glass 7W LED bulb that I ordered through Amazon and I knew was going to be clear before I placed my order. I am extremely happy with this bulb. It replaced a 13W Compact Fluorescent Light bulb (CFL) in a standard lamp that is the primary light in our living room. It definitely has the lumens to be a 60-70W replacement. Compared to the 13W CFL bulb that was in the lamp before, there is virtually no difference in lumens. As some people have mentioned, the light may be a little harsh depending on where it's going. For me, it went into a lamp that has a cream-colored shade and while the light is a little more white compared to the previous CFL (in the same lamp with the same shade), the difference is so minor that I don't think many people will notice much difference. Especially if it's going into a fixture with a shade covering it. If you are considering putting this LED bulb into a fixture that has no shade such as a bathroom vanity light, you might want to consider going directly to Priority Energy and Lighting to purchase the frosted version. As someone else mentioned, this LED bulb is a little big and it barely fit inside the lamp where the previous CFL easily fit. The LED bulb turns on immediately and there is no warm-up time or subtle flicker that some older CFL bulbs have. I could not be happier with this LED bulb and I would buy it again without hesitation. Since this LED bulb is in the primary lamp in our living room, we're saving 6W several hours each night compared to the 13W CFL bulb that we were previously using. I'm looking forward to when the price comes down so that I can buy more of this same bulb to replace other CFL bulbs that are throughout our house.
Update 11/23/10: We have been using this LED bulb for several hours every single evening now for over 6 months and it continues to work great. Zero issues and I would still buy it again without hesitation.

The INCU7W product gives great 360 deg light and will light an entire room with only drawing 7W of electricity. You and your family would not even be aware that you have an LED product in the lamp or light fixture as the color of the light is matched to the traditional incandescent light bulb. The bulb turns on immediately and will dim on electronic low votage dimmers easily available. This is the greatest LED replacement product for incandescent light bulbs and is very popular.

This product is exactly what it says it is, but I wish I'd looked at the description or picture more closely.
These work perfectly for what they are intended for, but note that the beam is rather narrow (36") and that the inside coating is reflective, rather than translucent. I bought these for a chandelier with translucent glass shields, and I didn't realize that translucent bulbs are really important for this use. These reflect a greater amount of light towards the subject and thus less into the rest of the room through the translucent glass. But that was my bad, not the bulbs. The bulbs are, as I said, exactly what they say they are and I didn't sufficiently appreciate what I should have for my application.

Well you either need this exact bulb or you don't. This bulb is used in a bath room fixture that is dimmed. I have found that other brands of bulbs sometimes "sing" when dimmed. GE's don't(so far). I couldn't find this GE bulb locally so I ordered from Amazon. Importantly the service was prompt and the bulbs were packed well and all survived the shipping experience.

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

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