1) Do you use top-tier vendor of LED chips and drivers?
A) For all of our LED fixtures, Hygea LED Lighting uses one of the top five LED chips and drivers suppliers to ensure the highest quality standards are met at all times.
2) Can you provide an IESNA LM-80 test report for your fixtures?
A) Hygea LED Lighting can supply LM-80 test reports for all of our LED fixtures – simply contact Hygea LED Lighting at Hygea and request our tech support team to obtain the testing reports.
3) How do I ensure that the maximum temperature range of the LED within the fixture is not exceeded in my particular application?
A) At the maximum operating temperature of any Hygea LED Lighting fixture, the maximum junction temperature of the LED is not exceeded.
4) What is the life expectancy of your LED fixtures?
A) The life of the LED fixtures varies depending on the specific product or application, and can be maximized by incorporating controls. Contact our technical support team to request calculations for your specific fixture.
5) Do you supply IESNA LM-79 test reports as well as .ies data files?
A) Yes – LM-79 reports are available upon request and our .ies files are published online for all product families.Both are produced by our NVLAP-accredited laboratory, per DOE CALiPER specifications.
6) Can you tell me the delivered lumens and LPW of the luminaire?
A) These values vary depending on the specific product and configuration selected. Please see our specification sheets and photometrics online for details.
7) Is the chromaticity in the ANSI C78.377A color space and does it hold steady throughout the life of the luminaire?
A) Yes – all of the LEDs used by Hygea LED Lighting are in the ANSIC78.377A color space. All are very stable over time and this can be verified by the chromaticity shift properties that are reported in the LED manufacturer`s LM-80 report.
8) Do you ensure that tight binning specs are maintained at your LED facilities so that the color of the light output doesn`t vary from luminaire to luminaire?
A) As with older technologies like HID and fluorescent, it is possible to have variation in the color temperature of individual luminaires. We employ tight binning specifications in our supply chain to limit this variation as much as possible and in some applications such as commercial indoor troffers and downlights, have industry leading specifications.
9) What is the power factor of your fixture? Do your LED fixtures consume too much power in the `off-state`?
A) The power factor and total harmonic distortion (THD) of the fixture are often confused with the power factor and THD values for the drivers, which are more widely published (our LED drivers all have a PF of >=0.9 and THD of <20%). The fixture power factor and THD values account for other components in the electrical circuit, but our fixtures also happen to conform to the same performance ranges as the drivers (PF of >=0.9 and THD of <20%). Off-state fixture power consumption is less than 1 watt.
10) Are your fixtures lead free, mercury free and RoHS compliant?
A) All of the electronic components within our fixtures and controls are lead free, mercury free and RoHS compliant.
