par 38 20k led
 

The bulb in question is: http://www.nanotuners.com/product_in...roducts_id=698

With summer just around the corner I am thinking this would be a good time to switch to LED, I am just wondering if there is anyone on this site that have tried the par 38 20k on their nano....

I am seriously considering ordering one but would like to hear some results before I take the leap. I currently have a 10g cube with 1 rbta and mostly softies and think 1 par38 with 80 or 60 degree optics should be fine at 12" above the surface.

If you have specs, pics and maybe what corals you are keeping and also what degree lense you used it would help me make the decision easier.


I have read a bunch of stuff online and I want some hard evidence with someone actually using this bulb, thanks in Advance.

That one in particular only comes in 40 degree optics so if you can find one with 60 or 80 it would be better as a single light source. IMO one would be enough but two would be better.

nethbet has like 3 of them over his tank. He seems to like them.

another user had 5 over his 20 long then tore it down to upgrade to a slightly larger tank. Forget his name though...

there are a couple companies that make those, nanotuners, boostled, and there is one more i believe.

I'm planning on picking up 3 to light my 34 gal tank after i setup my new 90.

You should look at a site called www.aliexpress.com you can purchase these same or better PAR 30, 38 lights for under $30 brand new from the manufacturer in china, the same places other vendors are getting them from and jacking the price 70%...

Just a heads up :-)

Keep note that you will need to search for manufactureres that sell single lamps.

for the price of those bulbs why would you buy just one get 5 for the price of one and keep the rest in stock , those are wickedly cheap .

hmmm now that i looked at all the bulbs there is no k rating so there probably all for home use (5-6500k ) thats a shame cuz they dont get any cheaper than that . Still might buy a bunch and convert my whole house over to led lighting , then i could get some 400w metal halides to off set all those savings.

You wil need to send the manufacturer an email though the site and they will customize any color for you with your desired optics.... No chagre.

Sorry mate I forgot to mention that :-)

Order the rapidLED par38's

btw people have burt sps with 40 degree, Personally I would look into the 60 degree

still debating between these or a 250mh for myself

btw....

all those "par38" listed on that wholesale site are using 1w bulbs. companies like nanotuners and rapidled use 3w cree bulbs, much better

Hi thanks for the heads up! Unfortunately most of those come in a warm white or cool white but I was looking for something more on the blue side. Also while I could try to solder some blue LEDs on there it wouldn't be worth my while to order 3-5 of these and do the work myself. Thanks though!
