Just collect my 4ft set this morning.
Setup once I reach home.
Very nice casing and very bright.
If the tube last this is really a very good buy.
Must thank Bro wil lee76 for sharing in this forum this lobang
Must also thank Bro Nim75sg for helping me to get the light
set.

Regards
Sherman

Also bought one unit of the 3ft fixture for my quarantine tank as it is too good to give it a miss due to the attractive promotional pricing.

Good buy ...

Bro Nim75sg,
is there any heating issue?? with the low profile of the light casing..I suppose the eballast will be like those in Dymax without casing, previously the eballast in dymax uses the casing as heat-sink so very hot when I touch the case...

If the casing is not hot (slight warm is fine) then it is really a good buy...any more 3ft fixture left??

The casing is slightly warm after I have ON it for 10 hours.

It's not like the heatsink when you touch the cpu, which is boiling

But one thing i noticed, whenever after I have ON it about don't know how many hours, when I come back to observe the tank, the lights are out, although the switches are still ON.

Only when I re-ON the switches the light is back.

Don't know whether is eballast problem or tube...

According to aquamarin, got 1 week 1-to-1 exchange

BTW, the temperature of my water doesn't really affect much by the heat released from the T5, probably due to the weather in Singapore recently.
U r refering to the reflective foil that commonly used for PL or FL. IMO it's not ideal to use it on T5 . As T5 design in such a way that each reflector is only for individual lamp, this is to maxmize the lumen output, & more reflector surface can be achieved. If u pack closely a few tubes in a small fixture, it certainly will reduce the efficiency of the lamp & may have a shadow cast by the adjacent lamp too. i read in somewhere that closely packed lamp could overheat the bulb wall from adjucent lamp, & will reduce lumen output & shorten lamp & ballast life.
