Why shoud I buy LED lighting instead of fluorescent lights ?
LED lighting products last 6-8 times longer, contain no toxic mercury & provide improved color rendering, no shattering nor flickering, instant on and of course higher quantifiable energy/cost savings.
How to express the output of lighting ?
Theoretically, efficiency is somewhat difficult to measure since there are no conventional or LED lamps are permanently
integrated with the optical system. A better measure of their performance is efficiency, in term of Lumen's of the same
power input, e.g. output of 300 Lumen with 12 Watts input. In case of Spotlighting, Center Beam Intensity should be used e.g. output 800 cd at 30 degree with 2.5W input, However, as for convenient purpose, some resellers are just presented the efficacy in Lumen/Watts.
What are the 2 key material used by the same production condition having difference performance & life span?
LED chips e.g. Grade A, B, non-grade & others beyond the specification . Power supply/module e.g. Efficiency, Safety, Durabilty.
What kind of LED chips used by various level of manufacturers ?
For MNC like Philips, Osram, Panasonic, CREE - Probably use the high quality/price LED chips from USA, Japan, Korea (Samsung) of best quality, say Grade A For Medium-end manufacturers, including Genii - Use Taiwanese LED of medium cost and of acceptable & stable quality, say Grade B
For most of the mainland China manufacturers - Try to use as low cost as possible, use inferior quality non-grade, or even something out the specification.
How difference in the cost of Grade A, Grade B, non-grade & out specification ?
Make it simple, to offer a general idea, Same type & specification, Qty of 1,000 pcs : Grade A : range USD 70 ~ 110 - narrower tolerance in voltage, color spectrum, good to superiour quality, longer life span Grade B : range USD 35 ~ 38 - with standard tolerance, acceptable to good quality, longer life span. Non-grade : range USD 12 ~ 24 - uncertain portion within standard specification, questionable quality & life span. Out specification : range USD 6 ~ 8 - basically waste from production, no guarantee of any specification, just lit on.
How to identify the LED chips with different grade ?
The raw material,wafer being cut into pieces of dices, which is the key material in LED chip. The better quality of wafer, the better dices , the larger the size of dice, the better, Grade A ( Better quality wafer or same quality wafer into less quantity of dice, of course, large in size ) Grade B ( Standard wafer with standard dice size under normal production & specification ) Non-grade ( Made from those low-yield wafer, or from remaining portion of wafer after main efficient portion has been cut with simplest test only, without precise sorting test of specification & just sell at lower price in lots ) Out specification (From disqualified wafer, just sell at a lower price in lots, even not all of them work i.e. lit on )
Why spotlight with beam angle ?
For different usage, e.g. 30 degrees to spot on a paint/demo unit, 60/90 degrees from ceiling to a table/lobby, better atmosphere.
Do Genii products contain any lead ?
Genii products are lead-free and ROHS compliant.
What type of aluminum & packing made from ?
All constructed from 100% recycled aluminum and 90% of packing.
Why Genii's LED tubes are with 2 types of AC input, 85~110V and 170~264V ?
Not with the problem of design, but an improvement of the higher efficiency of power supply, efficiency & life span.
Any precaution in installation LED spotlight ?
For reachable level of installation LED spotlight, DC 12V is desirable for safety purposes.
Ballast or adapter required for LED tube, down light or other lamps, same like fluorescent lamp ?
Not required. Ballast & adapters is only a kind of unusable waste of energy in using LED lighting. For replacement job, ideally disconnect those ballasts and/or adapters, mean further saving of electricity consumed. For New installation, none of these are required. P.S. All LED tubes are not working if they are not disconnected from the existing electronic ballast.
