haha.. not pushy but 50 watt briglux isn't my favorite, never even played with one. the 120 watt one I was playing with was retrofitting a 400 watt MH fixture for an arena so we could get a base line for coverage to see how many more we would need, and make the lighting even everywhere on the ice.
I did already conceed that the Cree is leading the way in efficiency and have never said anything to them not being one of the mose efficient LEDs out there,
what this thread is about is pour quality , not efficiency.. so about premature failures and output of the fixture which you do get from generic knock offs of the big brands. as far as efficiency is concerned realy who cares if your fixture costs 15 bucks a month to run instead of 12.50 well I am sure some one will care but when you were spending 35 to 40/ month for the MH its a mute point as long as you are getting the output you want.
this started off from some one saying that it is a garbage fixture because it is made in China, what we have tried to show while it is made in china it is using bridge lux LED, which are not bad LEDs, in fact they are very good LEDs maybe slightly less efficient that Cree but still a high quality LED. "made in China" doesn't mean junk but rather made to spec.. why do we make stuff in China because it is cheeper. factorys in china have come a long way.. most workers make a deicent living now days but compared to what we concider a diecent living yes it junk, but I am going by my buddies company and what he tells me when we got togeather last month while he was back in Canada for our friends funeral. He pays his employes 50% higher than the "average wage" for the area so he is far from a sweat shop. but because there is no unions and typical "lazy north american attitudes" more pieces get build for less money. he can even buy the parts cheeper because of the region he is in, I almost choked on the price he quoted me for Cree LEDs in my design, no way we could do it that cheep.
then Dez mentions there was no heat sink, and I pointed out you don't need a bulky aluminum one always as you can get thermal marterial PCB bonded to copper, aluminum, or other metal as an internal heatsink, then with fans your good.
if we had the resorses to do reflow soldering we could get rid of the stars the Crees are reflowed to, make our own board, and reflow the LEDs directly to it giving us way way cleaner looking fixtures, dropping the price quite a bit.
this is the way all the new onjes on the market are making them, vertex, ect... there is a company out here in Vernon or Kelona or around there that I have been talking to the guy. they already make lights like what we need but for plants so they have a real redish look to them, but they have been selling them for about 3 years now and it would be very easy to rebrand there light for fish tank. just got to change the colors of the LEDs ie.. get rid of the reds but theres are not dimmable ect.. just on / off but man were they ever lighting up the plants at the home show.
