I needed a new desk lamp to use at the dining room table when I spread out references for a large project. A normal table lamp simply did not provide enough illumination. As this is the first LED lamp I have ever owned, I was a little concerned that it would not be bright enough. Well, I was pleasantly surprised: it is quite bright. Also, the adjustable positioning features of this lamp allow me to point the light exactly where it needs to be. The lamp has three brightness settings; but I always use it (for reading) at the brightest setting.
According to the product description, this lamp produces 432 Lumens at 8.37 watts. I connected this lamp through a Kill A Watt (P3 International P4400 Kill A Watt Electricity Usage Monitor), and here are the power consumption readings: brightest setting 7 watts; middle setting 5 watts; lowest setting 3 watts. This is quite a nice savings, compared to ordinary light bulbs.
I bought this lamp for normal, every-day use; however, a month after it arrived, I had the opportunity to use it for backup lighting when the power line to my neighborhood was accidentally cut. I discovered that this LED lamp will run while connected to a modified-sine-wave inverter (supplied from a 20 amp hour battery). Since a CFL bulb cannot be operated with most modified-sine-wave inverters, this means that this LED lamp is a good choice for backup lighting. Since this lamp has even lower power consumption than a CFL bulb, you can maintain lighting on a battery-powered inverter for considerably longer.

I was looking around searching for a nice LED desk lamp. I looked at other online retailers but they were very expensive. I came across Prism-lightening randomly and saw this lamp and it seemed perfect and it had a much better price. I choose the metallic grey one with anti-glaring. The lamp stands out nicely in my apartment. The packaging was very nicely done and gave a nice first impression of the product I was dealing with and gave me confidence I made the right purchase once I put the thing together which was easy and fun. This was an awesome product, highly functional and aesthetically pleasing!!!! Thanks!!!Best Deals for PRISM TL-4300GR Energy Star LED Desk Lamp with Anti-Glaring Filter
I have had this lamp for around a month or so. Very nice quality. Good light for reading, studying. Very Stylish. If I could make one change, it would be to make the base just a little bit heavier ... that way when you adjust the angle of the arm it would be more secure. Sometimes the base lifts up off the desk when I am moving the arm. Other than that, very satisfied.Honest reviews on PRISM TL-4300GR Energy Star LED Desk Lamp with Anti-Glaring Filter
Summary first:I received the gray. An excellent color with aluminum accents. I think it looks better in person than in the pictures.
The base is plastic with metal inside and heavy enough for stability. The lamp is made of good quality plastic and some metal. Overall solid quality construction. The LED's are recessed in the thin lamp arm section so they don't shine in your eyes. The diffuser works well and evenly lights work area with no glare. Power consumption is very low at 8.4W on max brightness. The lamp is just barely warm after hours of use. Lamp control is by touch button similar to a touch screen on a smartphone. Touch button is lighted when off. There is no separate on/off button.
I love this lamp and would not hesitate to buy it again. The longer I have it the more I like it.
Light output: Max 500 lumen. For comparison 400 Lumens= 40W incandescent and 800 Lumens= 60W incandescent. Keep in mind that this lamps light is reflected down so it will appear to put out more light.
Dimming: 3 levels. No separate on/off, so you have to cycle down from high, med, low to off. No big deal for me. Touch control works well similar to a smart phone touch screen.
Light color: Halfway between warm white and bright white on the color spectrum. A good choice in my opinion. Not too white like office fluorescent lighting.
Light diffuser: Works well. You can easily see the individual LED's looking directly at them, but the lamp diffuser evenly lights your desk or work area. The LED lamp arm swivels about 15 degrees.
Adjustability of lamp:
1) BASE swivels only 45 degrees left or right. 90 degrees or more would be much better, but not a deal breaker for me.
2) VERTICAL arm adjusts nearly flat front or back. (almost 90 degrees forward and almost 90 degrees backwards.
3) LAMP ARM will fold down flush with the vertical arm and 45 degrees higher than horizontal. Sorry if that description is confusing.
4) LAMP ARM TILT is only about 15 degrees. This is enough tilt to keep the lamp from shining in your eyes.
Note: The lamp joint(s) do creek a little when brand new. This does not last long.
LED life:
You should NEVER have to replace any of the LED's. They are made of silicon. The same stuff as your computer microprocessors are made from (Intel) though the manufacturing process is much different. The built in power supply is much more likely to fail before any of the LED's.
Note: Not this model, but some models from this company have an AC adapter (110V-220V) that can be replaced if it goes bad. Prism TLC-4300BK Multi-Function LED Desk Lamp with Anti-Glaring Filter , Black
Power consumption:
OFF: 0 Watts
High 8.4 Watts
Med 4.4 Watts
low 2.5 Watts
Measured using Belkin Conserve Insight Energy-Use Monitor
Switched outlet: The lamp does not remember the last setting if used on switched outlet.
Emergency Lighting: Since this lamp uses so little power it can be used as emergency lighting if you have some type of emergency power source either generator or battery with 12 DC to AC 110V.
LED lighting costs have come down a lot but are still expensive. Still a good value at less than $100 considering the LED's will last a very long time, good light color, 3 light levels and excellent construction, materials and very low power consumption.
I also have the Prism TLC-4300BK (more expensive) that has 3 light color option and a few extra features. I always use it on the white color. Great lamp to, if you don't mind the extra cost.

i like this light. i don't mind the 'tap three times' to turn it off .. minor inconvenience.my wife has to use it and she is kinda picky. she loves it, too.
it's bright, doesn't monopolize desk space, is fairly adjustable.
minor gripes: no shades on it. i sit on the other side of it while watching tv and she is at her desk.
i had to add a shade so it wouldn't always shine in the corner of my eye.
light itself swivels forward and backward but not that much. should be wider swivel.
would recommend to others.
