I got my Coralight Aqualight 30" today (I switched the two 50/50 bulbs to two 6700K freshwater bulbs). But, I have an issue.
When I tried to turn it on, the lights just blinked for a split second, and stayed off. The fans ran when the front light switch was on (as it is suppposed to), but the lights would not come on.
I then switched out the 50/50 bulbs, and this time the back one would come on, and the front would light up for a split second, and then stay off.
I switched both bulbs again back to the 6700K bulbs, and both of them turned on fine. So I thought "okay, I probably just didn't have them connected tightly enough, and they are 'electronic ballasts' ... perhaps they electronically try and determine whether or not to supply power to the light based upon the connection."
To test this, I turned the back one off while leaving the front one on for a minute or two. Then I turned the back one on, and it flashed, and stayed off. I turned the front off, waited a minute, and turned it on, and it turned on alright. I then tried the back, and it turned on.
What's going on here? Is this alright (as in the "electronic ballasts" are doing their jobs) or do I have some sort of loose connection somewhere?
Right now the bulbs are both on on my 29 gallon, and boy does it look nice when they're on.
I just need to know if it is an actual problem or if I'm just not pressing the bulbs into the pin connectors tightly enough (though I think they're pretty securely in place). Also, the question arises when I'm not at home whether or not the bulbs will come on with the timer, or whether they will flash and stay off, which is definitely an issue.
As one last note, I noticed that if I switched either bulb off and then on in the span of a few seconds, neither do come back on immediately. But perhaps this is normal.
Sorry for the rather winded post.
Alright ... I just tried rapidly turning on and off both bulbs, and they seem to be working alright....
