TransInstrument's Aqua LITEcheck

[amteo]

Was surfing and saw this item. So, I was wondering if this can be used to tell the condition of the lamps, i.e. how far gone it is. I guess I want to know if the LUX intensity of the lamp will drop with usage. If it does, then this meter will be a better gauge of when to change lamps.

Are u getting one? If yes, do a review, maybe can do a Bulk order.

Thanks.

Still undecided if I want to get one. Need feedback first. Beside LUX level, I suspect color shift also happens as the bulb ages. If thats the case, this instrument can't measure it. Hopping someone with better knowledge can confirm.

Color shifts will happen when the bulb ages with the blue spectrum being reduced first but the red spectrum maintaining its output thus the bulb 'shifts'. This happens and affects higher K bulbs more drastically (e.g 20kk). If you are using reliable and proven 10kk (e.g BLV 10kk) and lower, the effect is not greatly seen. Measuring lux levels would be a good guide for determining when the bulbs need changing and also measuring the specific lux levels at different depths would be very interesting. How much is the tester?

One Question - If there is a color shift to red with age, will the lux level drop? If the lux level does not drop, then measurement of the lux level might not give a true indication of the serviceability of the tube. By the way, your example was with a MH bulb, I assume flourescent tubes (T5, T8, PL, etc) color shift the same way, right?

How much is the tester?

Don't know. But TransInstruments is a Singapore company, so the pricing should be lower than comparable brands like Hanna.

Lux will drop with age too for MHs, dunt know if FLs will color shift with aging but i know the lux will drop like the MHs.

Somehow the charts on the site shown that higher LUX are needed for macroalgae. And the LUX recommended figures are above anemone....!

I'm wondering the measurement of LUX may not be helpful in measuring Kelvin.

LUX has nuthing to do with Kelvin. Lux is the brightness of the light, Kelvin is the color temperature. LUX is quite useful to determine the end of life for a bulb.

For Luxmeter, try this.

For Luxmeter, try this.

How much is that?

The TransInstruments one around $80++

[jc85]

Ard USD50 from amazon.

[tineng]

so who is doing the bulk order?????

[amteo]

For Luxmeter, try this.

But is it waterproof?

Where did you see it?
