They're about 17% efficient with street lamp-like (bat wing) angle of radiation.I found a good deal on some surplus ecoplus 40w led clearlight replacement lamps ($30.00 each). Can anybody give me any idea how efficient they are compared to similar power sized cobs, T5s and 150w HID lighting? Unfortunately they are 6K temperature so use is limited to veg or supplements for flowering. I got a couple to test out, so far impressed. crisp cool white cree leds drawing 44 watts at the plug. No fan for cooling and only warm to the touch.
