Bro , Can send me a picture of your tank? How much you looking at? How old and the condition of the tank. Where to collect? Cheers

Bro, You so good. But I will need it for a period of time. I am making a study on the LED fixture as compare to a 400w mh

Anyone can recomend where I can get a reasonably price PAR meter

Looking for 2 ft tank that is more than 2 ft deep. If you are selling please PM me with picture, place of collection and the price you are selling

Bro, Sori for the delay.Was busy this 2 days . Anyway you can contact RS at 68653433 Cheers

No I am using P4. Will let you know the web Cheers

Yes waiting for them to be in .Should be this week

You need a Lux meter or a PAR meter to determine the light output when install above your tank of 2 ft water height.

You can get a 1 A 12 vdc adaptor. I think less than S$20 I will let you know tomorrow .I need to get the contact from my office

Look like is the LED problem. Can be a batch problem only.Maybe you can check with your supplier and see their feedback. I am using Seoul semicon so far no issue. My next batch of blue should be in this week.Watch for my update next week. By the way you can contact Achieva-Dialight for your constant current drive or LED www.achieva-dialight.com

RS you call or fax them what you need and they send to you Correct Sim Lim Tower. What you using the 12 volt DC for? If for your LED lite fixture the I need to know your total led configuration to decide on the size. If for project testing propose the you can get a variable 30 volt DC 5 to 10 Amp unit. I got one 10 A unit last week for S$170 Cheers

Bro, Why you want a 12 volt transformer? Transformer output is not DC. Most LED today is DC source. Anyway you can get from Sim Lim or RS

Oop bro Barra so sori to hear that. Did you use a constant current driver to run luxeon Vs? Not advisable to run direct from DC source.Any surge and the LED gone. How is the tank lite up like? Cheers

I do not think Sim Lim have. Someone is selling this constant current drive in Singapore. Let me check and get back to you. Bro, Can share your LED fixture status and some picture here?

Its not easy to calculate. Best the lite must come withlab test results. That is how many lumen or PAR at say a certain height. For aquarium it is best to have the reading through water of say standard 2 ft of water If such reading is not available the last thing is they have the instrument to show you the reading when the light is on

Take your time. Don't rush

Bro, That is great.

Bro, No offence. I use to think like you until I try them out and do some measurement.You need at least a lux meter or/and a PAR meter. Anyway most of the high power LED is either 12 vdc or 24 vdc. If you do not have a meter the minimum you can do compare is to run them side by side and compare. That is LED compare side by side with whatever lite you are replacing.

I do not think so. This is only 2*5w led. Lumens are close to a true measurement of output power and PAR is an estimate of available power for photosynthesis

Bro, Those led from Sim Lim Square are mostly not bright enough to penetrate two feet of water. I had try a few forthe last months and all fail the minimum requirement for an aquarium. If you are seriously looking for led replacement for your T5HO or MH aquarium light go to many of the online store and look for the latest high power led from Philip or Seoul Semicon Cheers

Except for the different in color and a slight different in light intensity The led lited portion which is on the left of the tank from the red monti leftward look as bright as the T5HO lited portion which is on the right side of the tank from the red monti towards the right side of the tank

Left 2*5 watt led with lens and 96 watt T5HO on the right
