LED floodlights are not cheap. Hogar Infantil uses many lights - I went on a tour with the maintenance man. CFL is the most cost effective for hallway and general purpose. A 50-watt WHITE LED flood would be great for outdoor area lighting.
Have not seen a "blue" colored CFL from GE. Pure white. And this brand is better lighting than what is found in USA Costco and Sams. Both the 26-watt and 10-watt GE lamps are very bright. The 10-watt GE is almost as bright as Costco's 26-watt.
10 of each wattage would make a heck of a nice donation. Wal-Mart USA has them.
Got NEWS for you about cheap LED lighting. The chips are severely underdriven so manufacruring can save lots of money by avoiding a costly larger heat sink. Being an M.E.E. not only do I understand this issue I design and make LED lamps from 5mm 20ma to a thousand watt unit under construction. Three 400 watt 24-volt Meanwells and four 120 mm muffin fans cool a 6 lb finned heat sink. Lexan and Pyrex lens.
The G.E. CFLs in Blue Boxes are the white CFLs. Mexicans hate warm white with a passion. I purchased a SINGLE LED warm white floodlight for sale. 54 5,000 K flood lamps sold in the last two months the warm white same brand is gathering dust. And we've been out of inventory for longer than a week. Bluish LEDs are also a loser. 5K is popular.
I drive my 10-watt chips at 9.6 volts, which means spec sheet milliamps. The difference between my lamps and store LED lamp brilliance is disgusting. The 9.6 volt lamps are for off-grid rural ranchos. Yes I use a PWM bucker with low dropout to regulate 9.6 from 12+ solar system volts.
