* 300 Lumens is not equivalent to 300 watts
* 300 lumens is roughly 40 watts
* Watts cannot be converted to lumens as watts is a value of energy used & lumens is a value of brightness. A standard 60 watt light is in the range of 700 - 800 lumens
* LEDs are spot lights, the light focus is narrow & radiates in 1 direction, which is why many comments about LEDs make mention of this. LEDs are brighter than other bulbs of the same lumens ratings since there is no light loss
* All other bulb types are floods as the light radiates in all directions. 'Spot' lights just use reflective surfaces inside of the bulb to redirect the scattered light out of the front of the bulb, creating a narrower beam
* Choose LED products that state the brightness in lumens rather than meaningless values like, 'super bright'

I bought this based on the description that it is equivalent to a 300 watt work light. When I plugged it in I was disappointed at how dim it was. It does have a nice cool white color, but for my needs it is nothing like my bright 300 watt halogen. The box states it is compared to a 175 watt. Even that is not even close. Maybe a 75 watt, no more.

Very good value.
By Ronald L. Watkins
I read all of the previous reviews on this product and did a lot of web research before I purchased this item.
Got mine two days ago and have evaluated and tested it. Is it perfect for everyone?, perhaps not, but I really like it.
The advertised specs seem very accurate, according to my tests.
Light output rating is right at the 350 lumens, and color is right at 6,800k (cool-white). Power consumption is the stated 6-watts.
So, How do you compare it to other incandescent units? I used a 350-watt, halogen work light of similar housing design that I have.
I used a professional luminescence meter to make my tests. The 350-watt halogen light measured about 2,000 Lux, at a distance of 24" from the source. This unit measured 1,400 Lux at the same distance (70-percent). That's very good.
Note that cool-white LED "light output per watt" range from 50-110 lumens/watt. This one is only 58 lumens/watt, so it's at the lower end of the range, but still very good value at this price point. You want higher light output efficiency, prepare to pay a higher price.
Light distribution spread is about the same as my old halogen unit. Very adequate for general work area lighting. You hardly notice the slight difference in light output.
After one-hour of use, the unit was still cool to the touch (room temperature), while the halogen unit would burn your skin to the touch.
Yes, the light color is slightly cooler, but not too blue. The rated CRI (color rendering index) is only 69, while you want a rating of 90 or above for accurate color work, but that's no problem for general work area lighting.
The unit is very ruggedly constructed and the only fault I found is that the power switch is rather small and somewhat difficult to operate. Looks like it can stand being banged around in a work truck environment with little risk of damage.
I'm so pleased that I'm ordering more.
