LED lights are the best available lighting product on the market.
They offer substantial energy savings and if you have any air-conditioning adding incandescent lighting is working against that by adding small heaters around your house.
The Marexim line of lighting offers great lumen to watt ratios (compared to incandescent lights) and provides a lot of light. These lights have been running strong and are quality made. I've gotten cheap LED lights from China and they have already fallen apart.
I've calculated the savings and these pay themselves back in less than 3 years and over the lifetime save an average of $1200 per bulb (at my current utility rate of: 33 cents / kWh).
I tracked down the specifications for this LED lamp and was disappointed to see 660 lumens / 22 watts, that's just 30 lumens/watt, I have LED lamps with three times this efficacy, and these days only buy LED lamps with at least 60 lumens / watt. No I don't own the Marexim PAR30 LED, I just felt it necessary to add this information, especially after seeing the previous review where one PRO was "high lm/watt".
EDIT: Seems I was looking at out-of-date specifications, and mauichris was kind enough to direct me to more recent and hopefully more accurate specifications. So based on the 840 lumens / 19 watts I found there, that comes to around 44 lumens / watt, which is closer to average when it comes to LED lamps. Overall their product line looks very nice, clearly an upscale brand, but with price to match.
