After buying LEDs by diode type online, instead of just whatever generic shit they sell at the hardware store for light fixtures, it really became apparent how trash most hardware store lights were. Not to mention many of the replacement LED socket lights are flickering from the mains frequency. The efficiency in random socket versions are crap compared to the high efficiency diodes you can buy if you look in the right places, often the store versions are around 60-100 lumens per watt, when you can get closer to 180-200 lumens per watt.
- ourlordcaffeine 7y agoCan you give any pointers? I'm finding it quite hard to find datasheets and spectral measurements for bulbs sold online, they really don't give consumers much information.
- butteroverflow 7y agoI know of a very good resource [0], although it is in Russian. But I think you can still make use of the comparison table [1]. Here are the rough translations of the columns: * brand; * model; * description; * price (RUB, divide it by 65 to get USD); * power in watts; * luminous flux in lumen; * efficiency (lumen / watt); * power of an equivalent incandescent lamp; * color temperature, K; * CRI; * light cone angle in degrees; * flicker coefficient; * supports switches with indicator lights; * overall rating (from 1 through 5, with 1 being lowest); * warranty in months; * can you still find it for sale? There are lots of information on each lamp if you click on the model name. [0] http://lamptest.ru http://lamptest.ru [1] http://lamptest.ru/results/ http://lamptest.ru/results/
