Battery Operated Remote Control Light Review

This little light worked ok for a couple of months and then died. Well made and easy to put up. Bought it for a dimly lit space but light was not really bright enough but sufficed. Not sure why it died but as it was not adequate for the task will not pursue it. Live and learn!

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.

150 LED PAR 38 Floodlight, White Review

150 LED PAR 38 Floodlight, White
Average Reviews:

I am converting a mill to a business. I had a bunch of the incandescent bulbs in recessed lighting. I wanted to shift the color in the room to natural light and reduce energy cost. These are the answer.
I tried other lousy vendors from "Amazon Partners" for securing these LED bulbs. These guys are wonderful.
As for the brightness, they are replacing 65w bulbs and I found the LED bulbs brighter than the 65w bulbs.
Color shift - These bulbs are a color shift to daylight. It is not the warm glow you get from an incandescent. I use these to supplement "Sola-tubes" and for night lighting. I have a large space for artists. I need this type of lighting. You may miss the warm glow of an incandescent when you switch to this bulb. If you are an artist, it is a nice substitute or filler for daylight.
Price - They are expensive, but the cheaper ones are not as nice.

Dimmable E26 A60 Standard Household Base 50 Watt Incandescent Light Bulb Replacement with a 6 Watt LED, Warm White, 1012ww Review

Dimmable E26 A60 Standard Household Base 50 Watt Incandescent Light Bulb Replacement with a 6 Watt LED, Warm White, 1012ww

I purchased this A60 Dimmable E26 Bulb because it specifically says 'dimmable'. Most CFL (compact fluorescent lamp) and LED lamps are not compatible with dimmer switches designed for incandescent bulbs. They will either be damaged immediately, or their life spans will be severely cut short when plugged into light sockets controlled by incandescent dimmers.
As it turns out, this LED lamps works very well:
- At 100% power, it emits a bright white light in the forward-facing direction. The color temperature is not quite as warm as a 60W incandescent bulb or a 'warm-white' CFL lamp, but is a lot warmer than the typical bluish light emitted from a 'pure-white' LED lamp.
- At the lowest power, the LED lamp dims down to less than 10% of its full brightness, while still maintaining the same color temperature. In contrast, a 60W incandescent bulb gives out a faint red glow at the same dimming level. (See my customer images for brightness comparison)
The dimming range of this LED lamp is superior to any so-called 'dimmable CFL' I have tried (which usually turns off below 30% power). However, there are several 'issues' you should be aware of. Some for this LED lamp in particular, others for LED lamps in general:
- This LED lamp contains a large heat sink that covers half of its body. The actual LED board is attached to the heat sink using two small screws. The problem is that their screw threads are all messed up and one screw fell out. Lucky for me I tested the lamp in downward-facing configuration, so I was able to spot the loose screw inside the glass dome. Had I tested the lamp in upward-facing configuration, the loose screw would land on the LED board and possibly ruin the lamp.
- The beam it produces is highly directional. The view angle is 165-degree, which is wider than a flood-light or a spot-light, but much narrower than an omni-directional (360-degree) incandescent bulb. What this means is if you use them in your chandelier with lamps facing upward, your ceiling will be brightly illuminated, but the area directly underneath will be quite dim. On the other hand, this directional beam makes it ideal for use in downward-facing recessed light fixtures.
- The total light output (luminosity) is only 260-300 lumens (*). Strictly speaking, this is only comparable to the luminosity of a 25-30W incandescent bulb. However, because the light from this LED lamp is concentrated in the forward direction, it appears much brighter than a 60W bulb - as long as you stay in front of the LED lamp.
Finally, let's consider the energy-saving claim of LED lamps. LED lamps currently on the market are 5-7 times more efficient than incandescent bulbs, but the price is very high at around $5 per watt. So it may take many years for the energy saving to offset your initial investment. For example: suppose you replace a 40W incandescent bulb ([标签:Content].50) with a 6W LED lamp ($30), and your electricity rate is [标签:Content].12 per KWh, then it will take nearly 7000 hours to make up the price difference. In contrast, CFL are 'only' 3-4 times more efficient than incandescent bulbs, but they cost much less. So if you replace a 60W bulb with a 14W CFL ($2.5), then it only takes 360 hours to get your money's worth.
This is not to say that you should not replace your ancient incandescent bulbs with more efficient light sources. Just that you must have a realistic expectation on the luminosity and efficiency claims of LED lamps in general. In some cases, CFL may be a better choice - just remember to recycle burnt out CFL bulbs properly.
(*) Update on June 16, 2010:
The product page now says "Light output: 380-420 Lumens".
Update on Sep 9, 2010:
I purchased my second LED bulb and it has the same brightness as the first one. So I can't tell whether the light output has always been 400 lumen, or this is just another example of creative 'Spec-men-ship'.

Dimmable Par20 5 Watt LED Spot Light Bulb Replacement for Incandescent Halogen Track Lighting, Recess Light, E26 Standard Screw Base, Warm White, 1321ww Review

Finally, a bright-enough LED par20. I replaced 50W halogens for almost the same light output. They dim great (Lutron electronic dimmer, don't know the model). They CAN be installed with halogens at the same time and will dim together fine, which is great for the undecided or for the ones who don't want to fully commit to a slightly colder color. (They aren't quite warm white, but close)
I'm sure that as my review ages, my rating will go down for them, but right now, these are hands down the best energy efficient par20 dimmables for the price. CFL dimmables do exist and cost half of these upfront, but they tend to die fast. Maybe I have bad luck, but dimmable CFLs are known to have much shorter lives when cycled often.
For me, the big win is that in California, energy is really expensive. For a typical bill, the last 100kWh of the month costs me 35 cents per kwh. These let me reduce electric consumption in kitchen lighting from 45kwH per month to 4kwH. That's $14 a month, or $168 a year. They'll pay for themselves pretty quickly, though I'm sure I'll leave them on more now.
The bulb is never more than slightly warm to the touch. My recessed lights are 18 inches above my head, so I could always feel the heat when under the halogens. It never bothered me, but with these, you won't get that.
Overall, the only downside for me is the slightly colder light temperature. Not quite as warm white as I'd like, but certainly not white. But the fuzzy feeling of saving money makes it warmer.
The light is a bit less diffused than a standard halogen, so it may create dark shadow spots depending on your setup. You can get around that by mix/matching these with halogens, and they'll still dim just fine.
