Contact our team at connect@gutwillen.com or call +91 89206 29396 for full specification sheets on any model.
2. Do you manufacture rechargeable or emergency LED bulbs? What is the backup time?
Yes. The Bright Edge Series LED Emergency Bulb 10W is designed with an automatic charging mode and a charging time of 8–10 hours, making it a reliable option for homes, shops, and commercial spaces that experience frequent power cuts. It operates across a wide voltage range of 100–300V, carries a power factor of ≥0.95, surge protection of 4.0 KV, and a CRI of ≥80, with a lumen efficacy of 100 lm/W. The housing is PC type and the operating temperature range is -10°C to +45°C. For dealers supplying areas with unstable power supply across North India, this is one of our most practical and in-demand products to stock.
3. What is the lumen output and efficacy of your LED bulbs?
Gutwillen’s LED bulbs deliver well-documented, product-verified lumen efficacy figures across every variant. The Bright Edge Series 9W delivers 105 lm/W, the 10W Emergency Bulb delivers 100 lm/W, and the 50W Bright Edge Series delivers ≥100 lm/W. The G-Luxline 5 Way LED Liner Light delivers 1,000 lm total at 100 lm/W at 10W. As a LED bulb distributor in Delhi serving dealers and project buyers, every figure we publish is product-verified and not inflated, so you can confidently quote these specifications to your buyers and institutional clients without hesitation.
4. What base type do your LED bulbs use?
The Bright Edge Series 9W and 50W LED bulbs both use a B22 base cap, which is the most widely used bayonet base type across Indian homes and commercial spaces, making replacement and retrofitting straightforward for end users. The B22 base is compatible with the vast majority of standard light fittings found in Indian residential, retail, and institutional installations. For specific base type requirements outside the B22 format, please contact our team directly to discuss your project needs.
5. What surge protection do your LED bulbs carry, and why does it matter in India?
Gutwillen LED bulbs are built with surge protection across all Bright Edge Series variants. The 9W and 50W Bright Edge Series bulbs carry surge protection of >4.0 KV and ≥4.0 KV respectively, and the 10W Emergency Bulb carries 4.0 KV surge protection. Voltage spikes and power fluctuations are a persistent reality across Indian electrical infrastructure, particularly in smaller towns, industrial zones, and areas with inconsistent grid supply. Surge protection guards the internal driver circuitry against these spikes, directly contributing to longer product life and fewer failure complaints, which is a critical spec for dealers who want to reduce after-sales issues and build lasting buyer trust.
6. Can I place a sample order before committing to bulk?
We understand that committing to bulk orders with a new supplier is a significant decision, which is why we encourage prospective dealers to get in touch with us directly to discuss sample arrangements. As a LED bulb manufacturer in Delhi built on long-term dealer relationships, we want every partner, whether a bulb dealer in NCR or a wholesaler in another state, to feel confident in our product quality, build standards, and packaging before making any bulk commitment.
